Our client filed his I-140 based I-485 about 4 years ago. He has attempted to contact the USCIS many times, even asking congressional inquiry, without any success.

He hired us last Wednesday to sue the USCIS for the unreasonable delay. We filed the lawsuit last Thursday and yesterday, his I-485 was approved by the USCIS.

We have an extremely high success rate for this type of lawsuit(it's called mandamus action).

If your case has been delayed by the USCIS, please seek competent legal advice to determine if you should file the lawsuit.
