Every year, thousands of international students on F-1 visas transition to Optional Practical Training (OPT) and face a sudden shift in their tax responsibilities. One of the most repeatedly saved and shared resources on the Reddit community r/F1Visa is the so-called “39 countries” list—a quick-reference collection of nations whose citizens qualify for special tax treaty benefits during OPT. The phrase Reddit r/F1Visa: 39 countries - OPT has become shorthand for a simple but powerful idea: depending on your nationality, you might owe far less US income tax than you expect, or even none at all.
This article walks you through what the 39-country list means, how F-1 students can legally reduce their tax bill during OPT, which countries typically appear on the r/F1Visa list, and the exact steps to claim your treaty benefits—all grounded in the shared experiences of the Reddit r/F1Visa community.
Where the “39 Countries” List Comes From on r/F1Visa
If you spend any time browsing r/F1Visa, especially during graduation season or the run-up to Tax Day in April, you will encounter threads titled “Does anyone have the 39 countries list for OPT tax?” or “Tax treaty countries for F1 OPT—am I on it?” The list does not originate from a single official US government document labeled “39 countries.” Instead, it is a crowdsourced compilation built from the IRS’s list of countries with which the United States holds income tax treaties, specifically filtered for those that contain a “student” or “trainee” article beneficial to F-1 visa holders.
Reddit users regularly refine the list based on three criteria:
- The country must have a bilateral tax treaty with the United States in force.
- The treaty must include a provision (usually Article 20 or 21) covering students, apprentices, or trainees.
- The article must grant a meaningful exemption or reduction of US income tax on wages earned during OPT.
Over time, the number most frequently cited on r/F1Visa is 39. Users who are planning their finances for OPT frequently search Reddit r/F1Visa: 39 countries - OPT to find the latest version, along with personal accounts of how the treaty worked in practice at companies ranging from startups to tech giants.
How F-1 OPT Students Actually Benefit from Tax Treaties
On OPT, you are still legally an F-1 nonresident alien for tax purposes during your first five calendar years in the US, unless you become a resident under the substantial presence test after a longer stay or through other changes. For most OPT workers, this nonresident status has a surprising upside: you can claim income treaty benefits that are not available to US residents or green card holders.
Each treaty is different. The most generous ones—like those for students from Pakistan, Germany, or some EU member states—can completely eliminate federal income tax on a certain amount of income, often for a limited period (such as the first $4,000, $5,000, or $10,000 of earnings per year). Others offer a fixed deduction or a credit. In many cases, if your total OPT earnings stay below the treaty threshold, your tax liability shrinks to zero. In other cases, the treaty simply reduces your taxable income, moving you into a lower bracket.
The financial impact is real. A Reddit user from a country on the 39-nation list recently shared that they saved over $4,500 in federal taxes in their first year of STEM OPT alone—money that went directly toward H-1B-related legal fees and relocation expenses. Conversations tagged with Reddit r/F1Visa: 39 countries - OPT routinely quantify these savings, giving new graduates a better sense of how much more of their paycheck they can keep.
The Unofficial List of 39 Countries (Reddit’s r/F1Visa Compilation)
The r/F1Visa community is careful to remind members that tax treaties evolve; some are renegotiated, and a few countries have seen their treaty provisions for students modified or phased out. However, the core list that consistently reappears includes the following (the most frequently mentioned by Reddit users):
Europe and Central Asia: Armenia, Austria, Azerbaijan, Belarus, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Luxembourg, Malta, Moldova, Netherlands, Norway, Poland, Portugal, Romania, Russia, Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Tajikistan, Turkmenistan, Ukraine, United Kingdom, Uzbekistan.
Asia and the Pacific: Australia, Bangladesh, China, India, Indonesia, Israel, Japan, Korea (South), New Zealand, Pakistan, Philippines, Sri Lanka, Thailand.
Africa and the Middle East: Egypt, Morocco, South Africa, Tunisia.
The Americas: Barbados, Canada, Jamaica, Trinidad and Tobago, Venezuela.
Reddit’s list is not identical to the full IRS treaty table because some treaty countries do not include a student article, or their student article applies only to government-sponsored scholars, causing r/F1Visa contributors to exclude them from the operational 39 countries. Before relying on the list, community members invariably advise checking the current IRS Publication 901 and the specific treaty text for your country—but the Reddit r/F1Visa: 39 countries - OPT threads provide the fastest practical starting point.
Common Questions from r/F1Visa on OPT and Tax Treaties
Do I still need to file a tax return if my income is fully exempt by treaty?
Absolutely. The treaty exemption does not remove your filing obligation. You must file Form 1040-NR (US Nonresident Alien Income Tax Return) and report your income, then claim the treaty exemption using the appropriate article citation. If your employer withheld taxes despite your treaty entitlement, filing will generate a refund.
What form does my employer need to stop withholding taxes?
Form 8233, “Exemption From Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident Alien Individual.” You submit this to your employer before you receive your first paycheck. On it, you cite the specific treaty article and country. r/F1Visa veterans stress submitting Form 8233 as early as possible, ideally during onboarding.
My employer ignored Form 8233 or didn’t know how to process it. Now what?
This is one of the most common rants on r/F1Visa. If your employer cannot adjust withholding in the current year, you simply file Form 1040-NR with the treaty claim and request a refund. Many users report receiving substantial refunds—often $3,000 to $7,000—after their first tax filing. The key is to keep your pay stubs and a copy of the rejected Form 8233, though a rejection is not required for you to claim the refund.
How many years can I claim the treaty on OPT?
Almost all student treaty articles apply for a specific period (commonly two to five tax years) starting from your date of arrival in the US, not from the start of OPT. r/F1Visa users caution that if you have already been in F-1 status for several years, your treaty eligibility window may close soon after you begin OPT. Always check the “time limit” clause in your treaty text.
Does the 39-country list apply to STEM OPT as well?
Yes. STEM OPT is still a period of F-1 practical training, so treaty benefits continue as long as you remain a nonresident for tax purposes and the time limit has not expired. A number of Reddit r/F1Visa: 39 countries - OPT discussions explicitly confirm that students extended their savings straight through the 24-month STEM period.
Real Reddit-Inspired Tips for Maximizing Your OPT Tax Treaty
Drawing from the most upvoted r/F1Visa threads, here are practical strategies that go beyond the theoretical list:
Start your research before you accept an offer. Use the IRS Tax Treaty Table or a CPA specialized in nonresident returns to confirm your country’s student article. Cross-reference with the 39-country compilation on r/F1Visa as a sanity check, but never treat the Reddit list as the final word.
Prepare a treaty packet for your employer. Many US HR departments are unfamiliar with foreign student tax treaties. On r/F1Visa, users recommend creating a simple document that includes a filled-out Form 8233, a copy of the relevant IRS treaty article, and a short cover note explaining that you are an F-1 visa holder entitled to exemption under the US-[your country] tax treaty. This professional approach frequently succeeds where casual requests fail.
Don’t forget about Social Security and Medicare taxes. Treaty articles generally exempt income tax but do not automatically exempt FICA (Social Security and Medicare) taxes. However, F-1 students on OPT are often exempt from FICA under the “student FICA exception” regardless of treaty status, as long as they are nonresident aliens performing services permitted by the F-1 program. r/F1Visa contributors remind new OPT workers to check their pay stubs for FICA withholding; if you see it, request a correction immediately.
State taxes are a separate issue. Most state tax agencies do not automatically follow federal treaty provisions. Some states, like California or New York, may not recognize all treaty exemptions. A perennial r/F1Visa topic is how to handle state taxes alongside the 39-country list—solutions range from filing a state return with a note explaining the treaty to paying a modest state liability even when federal tax is zero.
Use the treaty as a bridge to a stronger financial start. Many students emerging from the Reddit r/F1Visa: 39 countries - OPT discussions talk about using the tax savings to build an emergency fund, cover OPT-related health insurance gaps, or prepare for possible H-1B cap-gap fees. The community often pushes for financial literacy alongside tax advice.
Step-by-Step: How to Apply the 39-Country OPT Tax Treaty in 2024/2025
If you are about to begin OPT or have already started, follow this sequence distilled from r/F1Visa’s most consistent guidance:
- Confirm your eligibility. Visit the IRS “United States Income Tax Treaties – A to Z” page and click on your country. Locate the student/trainee article and check the income limit and duration.
- Gather documentation. You will need your passport, I-20 with OPT authorization, EAD card, Social Security Number, and ideally a letter from your DSO confirming you are a current F-1 student on approved OPT.
- Complete Form 8233. Enter your name, SSN, treaty country, article number (e.g., Article 21), income type (personal services), and estimated exempt amount. Sign and date.
- Submit Form 8233 to your employer. Ideally before your first paycheck. Ask for confirmation of receipt. If HR refuses or cannot implement, do not panic—retain evidence of your attempt.
- Monitor your pay stubs. Ensure no federal income tax is withheld once your Form 8233 is processed. If tax is already withheld, proceed to file a return.
- File Form 1040-NR by April 15 of the following year. Even if you owe nothing, file to document your treaty claim and claim any refund due. Attach a statement describing the treaty article, income source, and exemption claimed.
- Renew if applicable. Some treaty time limits extend into the next calendar year. Check before you automatically assume you are no longer covered.

FAQ
Is the 39 countries list officially recognized by the IRS? No, the IRS does not publish a document labeled “39 countries” for OPT students. The list is a user-compiled curation from the IRS treaty database, filtered to include only those countries whose student treaty articles offer practical income tax benefits during F-1 practical training. It is widely shared on r/F1Visa and should be verified against official sources.
What happens if my country has a treaty but it’s not on the 39-country r/F1Visa list? You might still benefit. The Reddit list is conservative; it includes only treaties with clear, broadly applicable student provisions. If your country has a treaty, check IRS Publication 901 or consult a US tax professional. Some treaties appear in the full IRS table but apply only to specific categories like researchers or government grantees.
Can I claim the treaty benefit retroactively for a previous tax year? Yes, generally you can amend up to three years back if you filed a return without claiming the treaty. File Form 1040-X (Amended US Nonresident Alien Income Tax Return) and include the treaty claim. r/F1Visa reports several success stories of retroactive refunds, sometimes with interest.
Do I lose my treaty benefit if I become a resident for tax purposes? Usually yes. Once you meet the substantial presence test or otherwise transition to resident alien status, most student treaty articles cease to apply. The r/F1Visa community often debates “resident vs. nonresident” scenarios during the first months of OPT, so be mindful of your cumulative days in the United States.
Why is the list so important to international students? Because US payroll systems default to standard withholding, which treats every new employee as a resident taxpayer. Without knowing about the treaty, a student from one of the 39 countries could lose thousands of dollars that they legally do not owe. The r/F1Visa subreddit and its Reddit r/F1Visa: 39 countries - OPT tag effectively democratize tax knowledge for a demographic that might otherwise never learn about the exemption.
Conclusion
The phrase Reddit r/F1Visa: 39 countries - OPT encapsulates a unique blend of community wisdom and real-world financial impact. It represents a living, peer-maintained list that has empowered countless international students to keep more of their U.S. earnings during the critical OPT period. Whether you are from Germany, Pakistan, Korea, Brazil, or any of the other treaty partner nations typically included, understanding and applying your tax treaty benefit can be one of the most financially rewarding steps you take as an F-1 visa holder.
Before you act, always cross-reference the latest IRS publications and your country’s specific treaty language. Use r/F1Visa for support, encouragement, and practical tips from people who have already navigated the same challenge. The 39 countries list will likely evolve, but the core lesson remains unchanged: a little tax literacy during OPT can translate into significant savings that help you launch your global career with confidence.
