My wife and I got the I-485 approval in March 2008. We filed the I-140 & I-485 in February 2006. The LC PERM was done by Rajiv’s law firm too. The I-140 was approved in 4 months without any issues.
Mostly I dealt with Prerna Mehta and Jitesh Malik. Both provide me excellent help and support during the process. Malik called me on my cell phone to answer my questions, and he was polite, fast and correct. Also, I praise Prerna for checking my documents and forms thoroughly and providing correction/feed back immediately.
My sincere thanks to you Mr. Khanna, for all the help and guidance that you gave us through out the application process. You were always ready to answer all my questions and I really appreciate all the help that you provided.
In future if I need any immigration help I would definitely go for Rajiv firm. If anybody has any help needed about immigration I would highly recommend Rajiv firm.
