1 我可能在国内工作一段时间，trip purpose写接受了一份工作可以吗？
-Yes, just put "Temporary employment in China".
要不要提供公司和具体工作合同之类的，-Not need.这样填会给人造成我无意在美继续居留的印象吗？
2 预计停留时间写六，七百天行吗？-Fine, but don't put more than two years.我目前也不知道呆多久。
3 寄出申请表后离境等打指模时再回来行吗？-Had better complete the biometrics before leaving. You may request expedited processing for biometrics appoitment. See:
