It’s been an absolute pleasure to work with Chen Immigration Law Associates or North America Immigration Law group for my I140 petition under EB1B category. I was amazed by their ability to understand Science and prepare an immaculate petition. A big shout out to their writer. While their expertise and existing reputation speaks to their over 90% success rate of Immigration Petitions, one particular thing that I am impressed with is their response time for every single question posted on their message board. Overall, I highly recommend to hire them so you can focus on your valuable research while they can take care of your GC filing process.
