I have designed a dual NIW, EB1-EA commercial package for those who are interested in applying NIW and EB1-EA at the same time by themselves.
By using your same set of NIW supporting materials (including recom letters), you can compose your EB1-EA petition letter for your EB1-a application if you meet any three of the requirements set forth for EB1-a. I have put it on test and it turns out successful.
If you interested in learing more detailes, drop me a line (yjy_wang@yahoo.com).
Sorry for bothering those who are not interested. Thanks.
Good luck to everybody.
