Important Notice - New Application Fees: Nonimmigrant and immigrant visa application fees for certain visa categories will change on September 12, 2014. All visa applicants must pay the fee amounts in effect on the day they pay, with the exception of Immigrant Visa application processing fees paid domestically to the National Visa Center (NVC), which will be effective as of the date of billing.
Fees that will decrease are not refundable. If you paid a visa fee before September 12, 2014 and that fee decreased, we cannot give you a refund.
Folks at the Law offices of Rajiv S. Khanna are thorough professionals. My application was for H1B and was handled by Sirisha Durgam. These guys have been very responsive and know what they are talking about. I would highly recommend their services.
