Applying for green card while on OPT

Question

I came across you website http://www.greencardforphd.com and found it very helpful. I am a Post Doc now, working on my OPT status (but applied for H1B visa). So can I do the self petition application for green card now (or do I have to wait till H1B approval)? I have attached my CV. Could you please, after reviewing this, suggest me whether I should go for EB1A or  EB2-NIW ?

Answer

Applying for i-140 does not pose any problem on OPT or H1B. There may be some issues involved during the 485 stage, if you apply while still on an OPT. We are not experts at this.  If you plan to apply for 485 at a later date (after you 140 approval), it is fine to start with your i-140 petition.
