just relax. the more nervous, the less chance to get the visa. when we applied J, we did not even have any evidence to show the tie link to China. the document we had are IAP66(i do not know what it is right now), passports, papers that published, marriage certificate and some photos. i think it totally depends on how lucky you are.
