I have some questions to ask, (so sorry if some of them are repetitive):
1) what's the meaning of the abbreviation TSC, which I have seen it here in some messages?
2) is it mandatory to attach photocopy of passport of the no USA citizen along with photocopy of the 2 year green card, the Form I-751 & the other photocopy docs?
3)the affidavit letter of support written by a US citizen friend of the couple must be notorized or sworn, or it can be just written & signed by the US friend of the couple without any notorization ? What's the difference (if there is) between notorized or sworn? (sorry I'm confused by that!!!)
I really appreciate if you guys can clarify me the above points!
Thanks in advance!!!!
