I am working in a company here in the US. They sponsored me a TN Visa for Mexican Nationals. The Company is going to renew my TN visa which expires July 25, 2011 sending the documents to USCIS. I married to a US citizen last January 15, and my wife is going to submit Forms I-765 (Application for Employment Authorization) along with form I-485 to USCIS too. I need to know if that is going to create a conflict with my TN extension process for continuing working here, I mean, can you request two cases for work authorization for the same person at the same time?
