Good morning nairalanders, please I have been invited to the United States for a Christian leadership programme for pastors or lay leaders. Truly my head is full and I don't really know much about it. Though the little I know is that it's a non-immigrant visa that I'm applying for; I will go to the US embassy's website to print a confirmation page before taking it to the GTB bank to pay for the visa-fee. But gathering the required documents is quite confusing. It's my church that is sending me out, but the organization over there is going to take care of everything including my hotel bills as well as my coming back. So, what are the necessary documents I needed to hold? After printing out the confirmation page to take to the bank, is filling the other forms online and booking for an appointment date too complex? Is it difficult to book for an appointment date like I was told? Please guys, I need your help, mostly on the necessary documents. Sincerely, I don't have much to spend on agents. I NEED HELP SIRS!

the embassy website is probably your best source of information in this case.
