US Immigration from Jamaica

Help !! So, I'm a bit concerned. I got a call a few minutes ago from the hospital I did my medical at. They stated that my medical will not be sent in time for the interview and that I need to come in to review the medical with the doctor. I asked if something is wrong and they said nothing detrimental. I'm not sure if I should be worried or not.. I'm thinking of changing the interview date. What could possibly be wrong? Thoughts??

My K1-visa interview is a few days away. Does having a co-sponsor lessen my chances of being approved at the embassy in Jamaica? Please advise. I'd love to hear about your experiences.

A bit confuse here. Will nvc forward your case then beneficiary pays necessary fees in their country and schedule interview or is it paid online to nvc then they forward case and create interview date for you ?

I JUST? noticed that I entered the first three numbers of my SSN on my I130 incorrectly. I sent it off in July and I got an email notification that it was received the very next day. Should I be concerned that my petition will be denied because of the error? I was going over all the paperwork with my husband while visiting and noticed the error. When sending off my petition I did send other information with my SSN on it, but now I am concerned about this error because it could make or break everything at this point. BTW I went to the USICS site and filled out an online form for typographical errors on petitions shortly afterward.

Does anyone has copies of their affidavit?
