About to file. Wife's on welfare. What am I up againstt?

[collinscurry]

Here are some facts:
1. Been married for over a year.
2. Wife is on welfare
3. Husband is a student on F-1 visa and still in status; visa expired 3 years ago. I-20 expires in 2016
4. Husband manages to work even though on f-1 and PAYS taxes
5. Both filed "marrid but separte" on their taxes because husband owes IRS due to mistakes on a previoes filing.
6. Both have sponsors for the "affidavit of support" since wife isn't eligible to sponsor.
7. Both living together with both names on lease, car insurance etc
8. Do I need a lawyer to help with the process? Many have stated it's unnecessary since husband is still legally in the US.


With all of the above, is there anything that might make filing for their green card difficult? Does husband have any challenges since he works(though shouldn't)? Would it be advisable to go ahead and file?
I'd appreciate feedbacks with post possible steps to take and any more ideas to make filing "deny-proof". Thanks.

If the sponsor is on welfare, there is a good chance of denail. The question is "If the person can't support herself, how is she expected to support others?"
