Hi Mukta,

It looks like you should be able to satisfy 3 out of 10 criteria for EB1A defined by USCIS (publications, being judge of others and contribution of major significance), see the link below. The only obstacle you may have is low citation count that may prevent you from satisfying the “wide acclaim” requirement of the second part of the two-part evaluation procedure. In the past, we recommended our users to explain low citation count by the small size of the field and relatively rare publications in the field, and move the focus to the recommendation letters. Recently, however, we noticed that more weight is associated with citations and less weight is given to the letters during the evaluation. In general, the rules for EB1A became harsher, so it would make sense to contact a lawyer in order to monitor the situation. Currently, they advise to choose NIW instead of EB1A, but for you, as an Indian national, it may make no sense, because the priority date for Indian nationals is currently retrograded to Jan 1, 2007, so there is virtually no reason to try it. In other words, even if your NIW I-140 is approved, you may have to wait for a decade before being eligible to file I-485.

Speaking of your husband, there is not enough information to say if he can be eligible for either category.
