Clients served by our National Interest Waiver Lawyers - EB2 NIW Attorneys - EB1 Lawyers

North America Immigration Law Group (Chen Immigration Law Associates) is a U.S. immigration law firm dedicated to representing corporations, research institutions, and individuals from all 50 U.S. states regarding I-140 immigration petitions. We specialize in employment-based immigration petition and have a proven record of high success rate for the categories of: EB-2 NIW (National Interest Waiver), EB-1A (Alien of Extraordinary Ability), EB-1B (Outstanding Researcher/Professor), and O1 visa(Alien of Extraordinary Ability Visa).

We keep close track of the latest immigration trends and regulations of USCIS (U.S. Citizenship and Immigration Services), decisions of AAO (Administrative Appeal Office) and judicial review opinions. The massive collected material contributes to the winning strategies for our clients' cases.

The key to our success is the way in which we present supporting evidence and provide the highest quality petition letters. With over 16,000 I-140 EB-1 ( EB-1A Alien of Extraordinary Ability; EB-1B Outstanding Researcher or Professor), EB-2 NIW (National Interest Waiver) and O1 visa(Alien of Extraordinary Ability Visa) approvals, our firm has acquired substantial information about USCIS decisions, which gives us substantial advantage over firms that only handle a small number of cases.

Based on hundreds of approvals every month and our close track of USCIS internal memoranda, AAO decisions, and judicial review decisions, we have unique insight into the USCIS adjudication trends. Not only do we apply this insight into our approaches to our clients' cases, but we also take the time and energy to carefully review all RFEs (Requests for Evidence), NOIDs (Notices of Intent to Deny), approvals, and denials issued on our cases so that we can further increase our understanding of USCIS strategies and decision-making processes so that we can advise our clients on the best ways to proceed with their petitions.

While other petitioners and attorneys may still use templates to draft recommendation letters or petition letters, our clients' recommendation letters and petition letters are tailored to their individual credentials to best persuade a USCIS officer that our clients meet the requirements of the category they are applying under and therefore their petitions deserve to be approved. To provide the best EB-1 and EB-2 NIW services, our law firm only selects attorneys who have received their professional Juris Doctor degrees from the top law schools in the U.S. and who have garnered rigorous analytical skills through years of experience.

With the responsibility of each case and our confidence of its success, we refund 100% of the attorney fee in the unlikelihood that the case is denied by the USCIS. Throughout our long experience in working in U.S. immigration, we have helped clients from all over the U.S. securing their green cards, including individuals working a a number of prestigious U.S. universities:
