Thanks for reply.
My case was transferred to Hartford CT (according to transfere notice and web page) on Dec. Then I file I-765 and I-131 to Hartford local office. But yesterday I knew, VSC transferred to MSC. Today I visited Hartford and asked about my application. The officer said, Hartfoed can not treat my application. I asked where is my application now? She said do not know. Maybe VSC or MSC. (Without checking computer) It is very nice service. I do not have receipt notice only I have copy of canceled check that I download from bank's web page (I do not know if this is offical).
No way to track.
Now I am thinking to file EAD to MSC.
I will lose $120 but it is better than delay and can not work.
