I would like to extend my heartiest gratitude to NAILG and especially Fanvin Shen for handling my O1A petition. I was under enormous stress, as my H1B 6th year was getting over on 4th July2019 and I did not have approved I-140. They recommended me to file O1A as a backup and I am glad I did that. I am really impressed that, they were able to prepare my O1A petition in less than three weeks and got it approved in less than two weeks. Hats off of Victoria Chen and her team for such an excellent service. I would highly recommend NAILG to my friends and colleagues for sure.
