I am currently a student one of UC university, 3rd year student. My expected graduation date is Spring 2012. USCIS has denied my father's I-360 on October 2010, but before they made the decision, my family received SSN and 1 year Work Authorization Cards that expire in April. My parents filed a Motion to Reopen/Reconsider and the motion was granted on November. But in December 20. The petition was denied.
So here is the time line:
Sept 2008 - Visa expired
July 2009 - Fingerprinted
May 2010 - SSN, Work Authorization rec'd (I-765)
Oct 2010 - I-360 denied, consequently I-485 denied.
Dec 2010 - Petition was denied
Now I am going all out to find a job. My Work Authorization expires sometime in April. If I get a sponsor, do I need to start working before my Work Authorization expires? Or could the company start sponsoring me so I can finish my Spring quarter? If my Work Authorization expires, could still find a sponsor? Once again, I am still finishing my third year. So what would be my best option?
Also when do I become deport-able? Is my current residency in America legal?
Thank you so much.
