Legal Question in Immigration Law in Louisiana

As long as the F-1 visa in your passport, issued by the U.S. Consulate, is still valid & will still be valid beyond your intended return date to the U.S., then you should be re-admitted without incident. If not, you might need to obtain a new visa at the U.S. Consulate while abroad. CBP will not admit you without a valid visa, which is entirely different than an admission stamp in one's passport.
