My EB1a I-140 was approved on Jun 10th. I received the approval notice (
courtesy copy) on Jun 15th. However, I just received email from USCIS that
the original copy which was sent to my attoney get returned by USPS since it
is undelieverable. My attoney changed address during the process and he has
noticed the address change to USCIS. He told me that it is not a problem
and he is going to local office to fix the problem as he believes calling is
always not working. Is it true or there will be some trouble for me? Thanks
for any suggestions.
