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 5,000 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.

    Got my I-140 approved under EB1A. Chen Immigration has been very thorough about every step of filing the case. They made me work on my summary till it is refined and I guess the outcome of this success pretty much depends on the rigorosity they followed. I Would like to thank everyone at North America Immigration Law Group for making my I-140 application successful, fingers crossed for I-485, Cheers
  • My EB2-NIW was approved on Aug 23 in Nebraska. This year, the NIW cases in NSC were processed longer than usual, ~10 months. During the past 10 months and preparation process, the lawyer team provides very accurate, prompt responses in every detail of your applications and questions. Their suggestions of recommendation letters, strategy and advice are so accurate that I feel completely comfortable and easy working with them. I am happy to recommend this firm to any other immigrants who have advanced degree.
