Hi Sukul Gunda, 1. You can't file I-485 until the visa availability becomes current for that category. No I-485, no EAD, no Advance Parole. No EAD for spouse. Sorry for that. I was mad with the paralegal of my sister's attorney who told me that even the nursing quota retrogresses, she can apply for I-485 and get EAD. That's not true. 2. There may still be possibility to switch to EB2. PERM approval process takes only two months (after you meet all the filing requirements). This may save several years of wait. Just get second opinion from another lawyer. There may be more risks than benefits :=|
