Kumar, take it easy man....
you are so tensed up and worried about the things. Take it easy don\'t worry too much things are moving slowly that\'s all. You need to have more patience, some times things won\'t turn up and speed up as we expected. Don\'t loose your good night\'s sleep on the GC man go and enjoy the life.
You might be happy to know that I just read another posting which said the INS stopped sending receipts last two weeks of October. Which confirms your no receipts > 10/17 theory.
Hopefully we should see few receipts in coming weeks.
Good luck.
