For many researchers, scientist, and engineers, the EB1-Extraordinary Ability petition is an excellent alternative to Labor Certification Green Card application, because it is much faster, and does not need to wait years for immigration visa number. Some applicants initiated both Green Card application processes, and then if an EB1-Extraordinary Ability is approved, they will drop the Labor Certification based application.

For the reference letters for EB1-Extraordinary Ability application, the worst thing is to obtain several reference letters which are all look same and may have the same repeated grammatical errors. The USCIS examiners will believe that these letters were actually prepared by the applicant, rather than by the actual referees. Rather, it is suggested to begin with a draft reference letter, and then discuss it with your referees by giving them general instructions.
