EB-2 visa application documentation usually involves proving the acquisition of an advanced degree through certifications such as transcripts and diplomas. Furthermore, applicants must show proof of having exceptional ability by presenting letters of recommendation, publications, and awards, for example.
Unless they’re applying for a National Interest Waiver, applicants will need to have a labor certification from the Department of Labor, as well as a job offer from a US employer. An experienced immigration lawyer can help you gather appropriate documentation.
