OPT EAD to green card

[Dmdm 0]

Hello, 
I am an international student here working on student OPT EAD which expires in 4 months and have an income of over 75,000. Married to a US citizen, my wife is a full time student and doesn't work hence, she can't sponsor me on I-864. 
I need to get my green card EAD or Green card to continue working where I am working now. 

Can i self sponsor on I-864? 
Can my wife use my income and sponsor me on I-864? If yes, what would be the process? 
If none of the above, any other way i can sponsor myself and save my green card application from falling apart? 

 

I just started working, hence I only have a letter of employment for myself and tax returns from my previous job. Would this Work, if my wife uses my income and I fill out I-864A ?

You cannot self sponsor your aos. Your wife will always be your primary sponsor. She cannot use your income as hers.  If she doesn't make enough or any money you need to find someone who will agree to be your co-sponsor.
