Can I leave and re-enter the US during my program?
If you need to leave the US and come back while your program is still running, talk to your visa sponsor before you travel, as there are steps to arrange first. See Arrival in the US for what you need when entering the country.
What happens once my J-1 has ended?
Your J-1 status ends on the last day of your contract. After that you're in the US on a grace period of up to 30 days to travel (see After program travel), not on an active visa. You can't use your J-1 to re-enter the US once you've left. If you leave the country during your grace period, you'll need ESTA, a visitor visa, or another valid entry authorization to get back in.
Can I visit Mexico, Canada, or the Caribbean?
Yes, but plan for the visa side. Once your J-1 has ended, you'll need a separate travel authorization to re-enter the US. Entry rules depend on your passport, citizenship, and country of birth, so it's your responsibility to check whether you're eligible to return.
What is ESTA?
ESTA (Electronic System for Travel Authorization) lets citizens of eligible countries enter the US for short visits without a full visa. It has a fee and can take up to 72 hours to process, and applications can be refused, so don't leave the US until your ESTA is approved. Apply only through the official US government ESTA website.
What about a Canadian ETA?
If you're flying to Canada, you may need an Electronic Travel Authorization (ETA), which costs around 7 Canadian dollars. Check the Canadian government website for eligibility based on your nationality.
What if I need a visitor visa?
If you're not eligible for ESTA, you may need a B1/B2 visitor visa to re-enter the US. This usually has to be applied for in your home country, at least a month before you travel, so plan ahead.
