Processing is talking too long

[memray]

Hello Every one.
My application was transferred to New York office from Buffalo office on January, 2012, and the status of my application was changed from pending to processing.
Also I received an email from New York office on May which asked to update my profile. Since then I have not got any message from them. So far my application passed 28 months.

So What should I do? Should I send them an email for updating my status?

I'd really appreciated if someone give me a suggestion.

Thanks
Mem
