all the reviews here are clearly fake.
After they take your money they will never help you again. We paide our fee in full: papers were filled and sent to USCIS with many mistakes, after they never spoke with us over the phone again, and were sending very few reply over emails. Also if at the end afyer over 1 year visa was not coming due to the poor papers and missing documents, they asked more money. At the end we didn't pay them any more money, we just went to a different lawyer who fixed all they mistakes. Do you a favor, give your money to a serious lawyer, not to Oltarsh that they have fake review all over the internet (check dates of reviews)
