I'm wondering when I apply for AOS, how does US immigration know what shots were given to my fiance and what are still required?

My fiance doesn't have any documents to support what shots were given to her at st lukes but I'm thinking maybe that is whats inside the brown envolope? She hasn't and won't open it but I'm curious how they can verify that if they themselves aren't the ones who open it?

hi there

when she enters the U.S. and hands over the envelope it should have her medical results inside...all that information get sent to USCIS..

before she leave her homeland get her to contact the medical examiner to see if she can get a copy of her vaccination sheet..

and i suppose when the copy of the vaccination sheet comes with the AOS they compare it to the original...

good luck
