A doctoral student does not automatically qualify for a green card because of PhD enrollment, and a student does not always need to wait until graduation. The correct analysis begins with the legal requirements of each research based category and the evidence that already exists when the petition is filed.
Often the first category doctoral researchers consider because it permits self petitioning and focuses on the proposed endeavor rather than a permanent job offer.
EB1A does not require a completed PhD, employer sponsorship or a permanent research position. The applicant must independently satisfy the extraordinary ability standard.
EB1B generally becomes relevant when the researcher has a qualifying U.S. employer, qualifying experience and an appropriate permanent teaching or research position.
The applicant must satisfy the requirements of the selected classification when required.
A stronger research record may justify waiting even when filing is legally possible.
NIW becomes easier to analyze when the proposed endeavor is concrete and extends beyond the dissertation.
The strongest category may change as publications, citations, employment and professional recognition develop.
Enrollment does not automatically establish underlying EB2 eligibility or any of the three NIW prongs.
Separate degree eligibility, research impact, the proposed endeavor, extraordinary ability evidence and future employment facts.
Not necessarily. The applicant must independently establish underlying EB2 eligibility and the NIW requirements at the relevant time.
EB1A does not impose a degree requirement. The applicant must nevertheless satisfy the extraordinary ability standard.
EB1B requires a qualifying U.S. employer, qualifying experience and a qualifying permanent teaching or research position. Many doctoral students do not yet have those facts.
No. Filing strategy should consider the strength of the current evidence as well as legal eligibility.
