Hi All,
I received RFE for different things (Employment verification, BC, Marriage certificate). (I don't think anything left for them to ask .. suckers..) I did not inform INS about job change and they knew it only when I replied for RFE.
Letter format : letter stating your current position, future employment position with the company, salary, skills you are using in your current job (same as in LC).
Don't know what made them to transfer my case to Chicago, which is like some office Andaman Nicobar Islands (which will be much better). Those guys will answer to your phone and they ask you communicate is by writing letter to them. U will never get response. You have to there personally and waste your entire day with no result. I stopped thinking about. When time comes it will come. Hope it will not happen to you guys. Good luck.
