First of all I would like to thank everyone for the good wishes and for all the help. I really appreciate it.
The IO was very professional and nice. He asked lots of questions like when was the first time that we visited USA, what was the purpose of the trip, how many times did we visit USA, when was the last time that we entered the country, when did we get married, what do we do, etc. No question was asked about affidavit of support or wages, I guess it is because I submitted my employment letter. He didn't ask for my HS diploma either.
...
Overall everything went well but there were two issues:
1) They were not aware that my daughter filed a petition, "fortunately" (thanks to all of you guys) she was with us; the IO told us to wait that he was going to try and find her file. After 5 minutes he returned with my daughter's file and mentioned that it was good that she was with us so another interview appointment was not necessary.
2) My employment-based AOS file was not there, it still is in the TSC (Texas Service Center). The IO said that it would take around 2 weeks for TSC to mail my file and that he needs to compare the two cases before the decision.
He said that everything looks good and that we should be receiving our GCs in 30 days.
That was it, now we have to wait and hope that our files are mailed from TSC soon.
Big thanks to everyone!
Congrats i2009. I'm so glad you were over prepared for all the things they asked for, kudos to you. I'm also glad you took our advice to take your kid with you...who would have thought such scenario would show up. I am positive you will receive your green card in no time. Congrats once again and here's to a fast receiving of the "magical" card
