1. What documents should I carry when entering the U.S. on an F-1 visa?

To enter the U.S. on an F-1 visa, you’ll need:

• A valid passport with F-1 visa
• A signed I-20 form (endorsed by your DSO)
• Your SEVIS fee payment receipt
• Your admission letter
• Proof of financial support (e.g., scholarship letters or bank statements)

Keep all documents printed and organized in a folder—CBP officers may ask to see any or all of them.

2. What questions will CBP ask me at the airport?

Expect CBP officers to ask:

• Which university are you attending?
• What’s your field of study?
• How are you funding your education?
• Where will you live in the U.S.?
• Why did you choose this particular school?

Answer calmly, clearly, and consistently with your documents.

3. Can I enter the U.S. more than 30 days before my program starts?

No. F-1 students are not allowed to enter earlier than 30 days before the start date mentioned on your I-20 form. If you try to arrive too early, CBP may deny you entry.

4. Can I be denied entry even if I have a valid F-1 visa?

Yes. A visa does not guarantee entry. CBP officers may deny you if:

• Your documents are incomplete or inconsistent
• Your SEVIS status is inactive
• They suspect you're not a bona fide student
• You can’t explain your program or funding clearly

Always carry a full set of updated documents and be prepared to explain your academic plans.

5. What happens if my F-1 visa expires while I’m in the U.S.?

You can stay in the U.S. legally with an expired visa as long as:

• Your I-20 and SEVIS status are valid
• You're enrolled full-time
• You don’t leave the country

If you leave the U.S., you'll need to renew the visa before returning.

6. Can I visit Canada or Mexico with an expired F-1 visa?

Yes, in some cases. If you're visiting Canada or Mexico for less than 30 days, and haven’t applied for a new visa while abroad, you may qualify for automatic visa revalidation. This allows reentry even with an expired F-1 visa.
This doesn’t apply to citizens of certain countries or those with denied visa applications. Always confirm eligibility beforehand.

7. Can I travel while on OPT or STEM OPT?

Yes, but you must carry:

• A valid F-1 visa
• An unexpired passport
• Your EAD card (Employment Authorization Document)
• A job offer letter or employment verification
• Your I-20, signed for travel within the past 6 months

Without these, you risk being denied re entry.

8. Can I re-enter the U.S. while on OPT if my visa is expired?

No. Even if your EAD is valid and you're employed, you cannot re-enter the U.S. if your visa has expired. You must renew your F-1 visa abroad before returning.
Visa renewal is typically done in your home country, but some students attempt it in third countries—this is possible, but riskier.

9. Can I renew my visa in a country other than my home country?

Sometimes. This is called “third-country visa processing.” Some U.S. embassies allow it, but many prefer (or require) applicants to renew in their home country.
Check the website of the specific embassy or consulate before planning your visa interview abroad.

10. Can I enter the U.S. if my course is fully online?

Generally no. U.S. visa rules require in-person or hybrid instruction. Fully online programs are not eligible for F-1 entry.
Your I-20 must reflect that you are attending a physical U.S. campus. Some exceptions were made during the COVID-19 pandemic, but most of those flexibilities have ended.

11. What happens if I'm sent to secondary inspection?

Secondary inspection means CBP needs more time to verify something—usually your SEVIS record or supporting documents. You may be asked additional questions, or your case might be reviewed further.
It’s not always a bad sign. Stay calm, answer clearly, and provide documentation as needed. If everything is in order, you’ll be admitted after the review.

12. What if I forget to get my I-20 signed before traveling?

You may be denied reentry. Always get your I-20 signed by your DSO before international travel. The travel signature on your I-20 is valid for:

• 12 months for most students
• 6 months for those on OPT/STEM OPT

If you forgot to get it signed, contact your school’s DSO immediately to explore options for express delivery or reissuance.
