The EB1b green card checklist below provides a general idea of what type of evidence is usually needed for an EB1b green card petition. To have a better understanding of this list, please read the EB1b visa overview and then go through EB1b requirements and documents to see the details of what is usually included or not included as evidence.

The overall emphasis on the documents and requirements/criteria of an EB1b green card petition is that international recognition must be shown. Independent expert letters are the main source of evidence for the EB1b green card petition.

The requirements for an EB1b green card petition are extensive and while ticking the boxes of requirements sounds simple enough, figuring out what items should be included and strategizing how the petition is presented is not. It is common practice and strongly encouraged to obtain an attorney for employment-based green card petitions. 

Alternatives to the EB1b Green Card Petition

For people who qualify for the EB1b green card petition (Outstanding Professor and Researcher), it is possible that the person can also qualify for an EB1a green card petition (Alien of Extraordinary Ability) which is less restrictive as it can be self-sponsored (where the person can pay and start the green card petition by themselves) and it does not require a specific U.S. employer just proof that the person will continue to work in their field of expertise. In some circumstances, it may be beneficial for the person to pursue an EB1a green card petition and an EB1b green card petition at the same time.

For people who do not qualify for the EB1b green card petition yet, the closest alternative would be filing a National Interest Waiver (NIW) with an EB2 green card petition. The EB2 National Interest Waiver green card petition would require the person to have at least a master’s degree (or its equivalent) or have exceptional ability (lower standard than the extraordinary ability in the EB1a green card petition) in the sciences, arts, or business, and the person would also need to show that their work will be able to benefit the United States significantly. 

Other alternatives would be the more commonly used employment-based green card petitions such as the regular EB2 green card petitions (Advanced Degree) and the EB3 green card petitions (Professional, Skilled, Other Workers). These types of employment-based green card petitions usually require a sponsoring U.S. employer and a PERM Labor Certification.
