I got my Eb1a 485 RFE last weekend. "Since you have changed geopraphic locations,please submit documentary evidence which established that you continue to be engaged in your field of extraordinary ability."
my questions are:
first, does this kind of RFE meed a lawyer to help handle the case?
second, 虽然我用的技术没变，但是申请140时， 我的专业是植物， 现在转到了医学院做癌症的细胞生物学，怎样回答他们的问题呢？
Third, do I need more refrence letters or just the present and past boss' letter should be ok?
Aany help would be greatly appreciated.
