Pakandi, yes you are taking a chance when going thru Deshi consultancy. I have heard that the ordeal could be mind-numbing as well as traumatic. You can file 485 on your own when you get there. No monies involved for lawyers and crap except for 1000 bucks or so filing fees under the new fee regulation. you need one support letter from the employee. I-140 can be filed for 300 odd bucks under new fee. Correct me on this. you need one letter from the employee and financial papers. Labor is electronic filing. The cost runs only for Ads and some other nominal fees. Good Luck!
