Why July 13? why not July 1st, ask yourself why not April 27, why July 13th?
Who told you that INS will approve strictly on the basis of RD,We have had enough discussion about this and no one is sure about whether they process RD or ND or combination of both, luck and things like that. So you are not the only one there are 100\'s if not 1000\'s of people who are suffering with this fuzzy logic.
