謝謝,還有問題麻煩您回答

他們要我通過email提供publication list,現在工作和以後工作description of research,現在的雇主證明信,還有就是trip plan.

-H1B1`holder does not allow to have immigration intent, so you have to address that after you finish your work in US, you need to return to Singapore (trip plan) and your backgound has to match your job (descripttion of research), and of course you have to be hired by a US employer (雇主證明信).

我的trip plan沒有說我工作完就回到新加坡,隻是把我的機票信息發給他們,這樣可以嗎

不懂他們僅僅是要補充材料而已還是要仔細的security check.一般需要多長時間.我可以打電話或者email大使館詢問進展嗎,

請問有沒有經驗回答這個問題,謝謝
