HI, My wife's 12 month OPT started on Feb 9 2012 , she started working as unpaid intern with company A(everified) from May 6 th 2012. She is planning to join company B(everified) early next month . Are there are any specific tasks that need to be completed by company B(create a everify case , I -9 etc..) before hiring (it will be unpaid initially and my wife will apply for STEM 17 month extension with company B some time November)? Also , Company A , did not fill an I -9 or any e -verify process for her, which i believe is ok , since there are no such requirements during 12 month OPT and she was not paid , your thoughts? Any common RFE's she need to be aware of when she is applying for STEM extension? thanks much!
