Mr. Khanna is very knowledgeable. They are very prompt in replying to all the queries both from the clients and the USCIS. Mr. Khanna and his team knows how to put the application together and, if necessary, how to answer the queries and RFE's from USCIS. I am very satisfied and would recommend them for anyone's immigration/non-immigration related applications to USCIS. They are a fine group of immigration lawyers.
