I filed marriage based I-485 in May 2005. Moved from NY to Michigan, so my case was tranfered. Just checked my status on CIS web, it was last updated in Oct. 2006, saying my case is now at the Missouri service center. There was no missouri listed as a service center, only a district office in St. Louis.
Should I do anything? Why is my case delayed so much. I saw many applicants who filed later got approved.
Thank you!
