Dear JKC,
Your sponsor needs to provide the following.
1- The Afidavit of support form I-134 filled correctly and signed
2- Tax declaration forms for the fiscal year
3- If they are working, they need to show proof. My sponsor is a nurse and she provided a letter from the hospital where she works
the bank statement of the sponsor is not required as information about saving, insurance, property is filled in on the I-134
Please make sure the person has not been providing affidavits for other people within that year or period.
also, make enough contact with your sponsor as you need to show proof that you know him/her or they know u very well and will be willing to provide for u while ur there.
i work in a bank, but i did not bring along a bank statement as i was not asked to bring one. i had it in my bag though. someone infront of me submitted it and the lady returned it to him saying they did not ask for that.
Stay cool, be confident, and PLEASE NO FRAUDULENT DOCS. THOSE PEOPLE ARE TRAINED TO SNIFF YOUR MIND. Relax, the guy is just another human being like you, waiting to grab a beer that evening after the day's work..
