Bobik,
hi and welcome,
I got couple of questions and comments:
One of the requirements for most of the AOS applications especially family based AOS is financial ability. You need to prove that you are not going to be a public charge. That will be shown by the level of education, history of employment, credit history and score (if any), age, health, marital status and etc.
there is a fair number of posts about this in this or last year's forum which you can read and learn.
It is totally up to the I/O at you local office to decide whether you need an employment letter or affidavit of support or not. Some of the F students last year did not have it and were fine and some had to get it. The fact is, you do not have to have it ready to be sent with your application. You may tho, but if you don't then it is up to the I/O to ask for it or not. If I/O feels like you need one, then you need to bring it to your interview.
here is a couple of questions:
what is your level of education: are you a grad or undergrad?
have you ever worked here as RA, TA
have you been receiving any financial support through US banks?
Do you have a SS#?
Are you single, married?
Do you have a fat bank statement?
anyways, you get the idea, read more about it in previous posts and last year's forum.
Good luck
