I received a complete official transcript and a letter confirming that I have completed all the requirements of the master degree. The university's next graduation date is Jan-30 2009 when I will get the diploma. Can I apply for EB2 on my complete official transcript or I have to wait until I get the diploma.
Generally speaking, under immigration law we focus on when the degree was completed - NOT when the formal diploma was conferred. Speak with your lawyers.
