The website of the US embassy mentions that you NO LONGER need bank statements, land titles, letters of invitation, or any similar documents. So, no need to worry about getting bank statements or land titles certificates.
All you need now are :
- Any prior passports
- DS-160 confirmation page
- Application fee payment receipt (SEVIS and DS-160)
- Photos and I-20
I believe that this has made the process tremendously easier as getting bank statements and land titles certificates were the most difficult. The documents listed above does not require much hard work to get it. So, yeah..things are getting better.
