Hey, I have a question that I've been trying to find the answer to for a while now, so I'm hoping someone on this forum will be able to help me out

I recently received my J-1 Visa for America, my question is regarding return flights and the visa period.

I'll try explain it a bit more clearly:

My J-1 visa is for a student exchange for 1 semester. It is valid between: late August and mid December. (Not including the 30 day grace period on each side).

My flight to America leaves in late July (which is within the 30day grace period before classes). However my return flight is booked for the mid February (outside the 30 day grace period after classes finish).

However I am planning to leave America and go to Mexico or Costa Rica around mid January (when the J-1 Visa grace period expires), and then return to America a week later using the Visa Waiver Program, then in mid Feb leave America.

So my question is, while trying to get into America will the officer reject me from entering because my return flight date is booked for after my J-1 Visa expires?

I hope that makes sense, if you have any questions please feel free to ask.

Kind Regards,
Peter
