Não há "trânsito" para os EUA. Infelizmente, você precisa de um visto legal para entrar. No entanto, existem algumas ressalvas para isso.
Em primeiro lugar, o seu visto expirou? Se sim (como o seu), você precisa de um novo:
If your visa is expired or you have already used the number of entries you are allowed, you will need to apply for a new F-1 visa in order to re-enter the U.S.
No entanto, se você estiver apenas visitando alguns países, existem algumas exceções :
If you are traveling only to Canada, Mexico or the Caribbean (except Cuba and Bermuda) for fewer than thirty days, you may return to the U.S. with an expired F-1 entry visa in your passport
Eu fui caçar para ver o que eles definiam como 'Caribe', mas infelizmente, é não na Colômbia .
If your U.S. F-1 or J-1 visa has expired...limited to only U.S. territories, Canada, Mexico and adjacent islands of the Caribbean, and your combined visits to these countries must be limited to less than 30 days.
