JT09

If he doesn't enter the US before his visa expires, then he would need to contact the consulate for an extension of the expiration date. If they don't want to do that, it will expire and he will have to start over.
He would only need to do a sputum test again if his chest x-ray shows possible TB.

The answer should still be "no".

Got the same thing with my father. He needs NBI letter of explanation. I received an email from USEM regarding the instructions so i told my dad to print it and bring it to the NBI the 4th floor of what the previous person posted it, i will try to follow the steps of what she did but i hope it wont take too long since their medical will expire on january.
by the way, whats the number of the USEM?

I believe that is the another fee I forgot exately what it is processing fee or something fee that you can paid either at the interview or at the POE it is better to paid it at interview it sounds like if they kept his pass port he has been approve
paid no attention on the above posts as some people on here do not have a clue

Usually, no.
If he is married he needs to submit his NSO marriage certificate and proof of termination of previous marriages (if applicable).
If he is still single (unmarried) to this day then it wouldn't hurt to bring a CENOMAR just to prove his marital status.
