You need to get a good lawyer onboard.
1. How long were you in school before you lost status?
2. Why did you lose status?
3. Did you marry after losing status? Or did you lose status right after marriage?
It sounds like you came in around 2006 as a student, lost your status, met a woman, fell in love, decided to get married and then married the same year.Then waited for two years to file for AOS.
Then you divorced in 2010, met another woman, fell in love, decided to get married and then got married the same year. Do you see where i'm going? That is why your lawyer told you to wait for 2yrs before filing for AOS. To spread out your timeline. USCIS may view you as a GC digger.
Evidence of bona fide marriage:
It sounds like both of you are currently out of work? right?
-Affidavits: Affidavits from family members serve you very weak evidence.
You need affidavits from reputable people.. like a church pastor, a family physician, and maybe neighbors. Everyone know that family member can do anything for their daughter or son in-law.
-Since both of you are not working, do your bank statements have any significant amount? Or any significant activity? Having a joint bank account with no money in it or no activity will hurt you.
-Do you own any major property together? Like a house, stocks/bonds or a car?
-Do you have any joint debt? e.g credit cards, car loans, mortgage, line of credit?
-Do you have any more financial connection other than the bank account? Like a bank CD? joint retirement account? Joint memberships (like gym)? basically things that show long term commitment?
When you guys were working, did you have mutual medical insurance? or do you have mutual medical insurance right now?
Please be well prepared. I know money is probably tight since both of you are not working right now. However, I believe your case needs undivided attention from a competent lawyer. Probably one that will be willing to accompany you to the interview.
If you have to borrow money, do it. You will easily pay it back one you are done dealing with USCIS. If you go to the interview ill prepared, UCSIC will skin you alive...
Be prepared to explain why you fell out of status and what you did to try to get back on status. Have a very good reason why you failed to complete your studies.
Do you believe in GOD? You need to pray and seek His intervention.
I wish you all the best. Gather your evidence, and consult a good lawyer.
Again, good luck...
