I know this may sound like a dumb question.But who ultimately give the visa,the NVC or the consalate abroad ? And how would my fiance know that his visa is ready ?

after your case complete at NVC it will forward to consulate in your spouse country.
the consulate will then set up the interview after the interview they will either approve visa your denied
after the NVC it all up to the interview

The consulate abroad issues the visa.

Your fiance will either be told to return and pick it up or it will be mailed to him.

Since a person needs the visa in there passport when they present themselves at a border crossing post... it would be difficult for them get it if it was issued inside the USA....

I know that.I was just wondering if they give it there or do they send it from here.Thank you for the enlightenment.

FELICIDADES! I'm so happy that you finally got your NOA-2. For Panama there is only a Packet 3 and that packet has to be picked up by your fiance. But, to make things easier for him, call the NVC so you can get your new case number and ask when they sent the paperwork to Panama. Una vez que este en Panama entonces dale esa info a tu fiance para que el lo vaya a recoger, it'll take approx 1 month for that packet to reach Panama, maybe sooner. Also, when he goes to pick up the packet, he can ONLY go on Mondays and Wed between 8-11. In the packet he'll find some forms he has to fill out and turn in so that way they can schedule him an interview. Also, the Medcial exam, record policivo and the I-134 is stuff he has to take to the interview. It sounds a little confusing but they'll explain it better at te embassy when he picks up the packet. Good news he doesn't need to translate any of his documents, they can stay in spanish! And that's it! you're almost there girly! I'm sooooo happy for you! if you have any questions let me know. My fiance just picked up his packet on monday and he's turning in the forms next week on monday, I'll keep you posted!

Gracias paisana.No sabes como me siento ahora.Estaba tan tencionada,y ahora me siento mil veces mejor. Do I have to send him anything to bring to the interview ?

Proof of ongoing relationship (pictures, e-mails, phone logs, chat logs, etc), I-134 and supporting documentation, letter of intent. Thats what I can think of off the top of my head. There may be other things outlined on the packet3 when your fiance gets it.

ok when he picks up his package, he has to fill out some forms, and once he fills out his forms he has to take it back to the embassy. Entonces, there they will tell him that he will need to bring: the papers from the medical exam, the I-134 (with the bank statements, tax transcripts, letter of employment etc) the I-134 is what you have to send him in addition to sending him proof of ongoing relationship like pics, and another letter of intent of marriage. At the embassy they'll also answer any questions he may have. pero es asi, for Panama after the NOA-2 is approved it's not that complicated. if you have any other questions let me know, right now we're at the point where he has to turn in the paperwork adn they'll assign him an interview date
cuidate!
