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:

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.

Approval of each case is the goal of our law firm. The key to our success is how we present supporting evidence and the high-quality petition letters based on systematic knowledge and comprehensive database developed by our firm. To provide the best immigration service, North America Immigration Law Group only hires attorneys with J.D. degree from top law schools.

We have one hundred percent confidence in our capability to successfully represent our clients, and we are the only U.S. immigration law firm with refund policy on I-140 petition. This is not an empty guarantee but specifically laid out in the attorney-client contract and is binding on our law firm.

We are pleased to announce that North America Immigration Law Group has so far received over 4,000 EB-1A, EB-1B and EB-2 NIW approval notices. In 2014 and 2015, the approval rate is 98.22% for cases using our Approval or Refund® (money back guarantee) service and 96.95% for all kinds of services.

For NIW cases, the approval rate is 99.18% for cases using our "Approval or Refund®" (money back guarantee) service and the overall approval rate for all NIW cases is 98.47%.

For EB1A cases, the approval rate is 97.25% for "Approval or Refund®" (money back guarantee) service and the overall approval rate for all EB1A cases is 95.27%.

We are one of the leading U.S. immigration law firms providing the most comprehensive services for EB-1/NIW petition with a large volume of approval cases and high approval rate.

*The number of approval notice for EB1B cases is under-estimated of the total EB1B cases we successfully petitioned because many EB1B employer petitioners did not submit G-28 and we are not the attorney on the record.

*Our approval rate is 98.47% for all NIW cases and 99.18% for "Approval or Refund®" (money back guarantee) NIW cases.

*Our approval rate for all EB-1 cases is 95.36% and 97.21% for our "Approval or Refund®" (money back guarantee) EB-1 cases.

*The approval rate statistics only include cases that were originally filed by our law firm and exclude RFE (Request for Evidence)/NOID (Notice of Intent to Deny) cases that were taken over in the middle from other law firms or DIY clients.

*In 2015, all our EB1B denials and many of our EB1A denials were issued by the same immigration officer working in Nebraska Service Center. This officer holds a significantly different adjudication standard from the rest of the officers. Without exception, the officer firstly issued a generic template NOID (Notice Intent to Deny) or RFE (Request for Evidence ) without addressing specific evidence submitted or raised specific challenges. After our response, the officer issued another template denial, without addressing any information in our RFE/NOID response.

*Most of the denied NIW cases are from the same immigration officer working in Texas Service Center, who, similarly, always issued template RFEs (Request for Evidence) and denials without addressing evidence submitted. Clients with similar credentials as those in the denials were able to get approvals from other officers.

    I would highly recommend working with Chen. I got my approval for I140 two days ago and all the process went very smooth. They know what they are doing, checking status everyday was only stress I had to take by myself :), cant help that... Right!!!! Rest all was taken care by Chen and they helped preparing all the documents, letters, SR etc. Very professional and prompt response is the key!!

I would like to highly recommend Chen Immigration for green card processing services. They were very professional in preparing all the documents for my case, and placed importance even on the minutest detail. I had my case approved in 2-3 weeks under the EB-1B category. I am very much satisfied with them. When it comes to your green card process, you can definitely count on them. Thank you very much, Chen Immigration for all your support and help in my GC process, and for providing very reliable service throughout.
