I have been successful in my application (Do-it-by yourself) for both the J-1 waive through an interested American government agency (the IGA) and the EB1B Green Card. As the international office of my University said that my case was one of the strongest self-made case among. There are quite a few techniques/methods that can greatly enhance your application
I have kept all set of the documents and if you need some information please feel free to send me e-mail me at riverxy01@yahoo.com
