Service Center: Texas Service Center (TSC)

Case Summary:

A well-known postdoctoral fellow from China engaged the services of North America Immigration Law Group ( to file an EB-1A (Alien of Extraordinary Ability) petition on his behalf. Our legal team and support staff did everything we could to convince the USCIS that our client’s work is of great importance to the United States. Just 6 days after we submitted the petition on our client’s behalf, Texas Service Center granted their approval.

Premium Processing:

Such rapid adjudication was largely thanks to Premium Processing (PP). This is a paid option offered by the USCIS. By paying $1,225 more, petitioners will have action taken on their cases within 15 days instead of 4-9 months. Although PP is an excellent option for petitioners who are reluctant to wait several months, PP isn’t for everyone. Only certain EB-1, EB-2 and EB-3 visa categories get to enjoy rapid adjudication (EB-1A is one of them).

Submitting an EB-1A petition:

It is no secret that EB-1A is upheld by a very high standard of law and that it has the lowest approval rates. However, with a strong petition packet and sufficient evidence proving the importance of his work, our client’s chances of getting an approval notice were high. Here are some of the key points that we focused on in preparing our client’s EB-1A petition packet:

  1. Professional Achievements: When we filed the case, our client had published 14 scientific articles that had collected 876 citations. He had also assessed the work of his peers on 30 occasions, which proved that his insights are highly regarded by other biomedical scientists.
  2. Peer Support: In support of our client’s EB-1A petition, five other experts in the field of biomedical science furnished us with recommendation letters. These letters stated the importance of our client’s work not only to the field but to the nation as a whole. Here is a quote extracted from one of these letters: “He is one of the most important researchers working today, and it is in the interest of the United States and its citizens suffering from cancer that he is able to continue his research.”
  3. Research Outcome: In order to prove to the USCIS that our client’s work is of great value to the country, we first had to understand it. We did this by carefully reviewing our client’s research summary (which he wrote and submitted to us) and concluded that his findings on cancer research and bioinformatics greatly impact the U.S. medical sector.

Becoming a permanent resident:

Now, the only thing standing between our client and permanent residence is the I-485 application. As the final step in green card proceedings, an I-485 approval means getting a green card. We wish our client well with this final step and thank him for working with us.
