In-principle approval 签证问题-去NUS工作的签证问题今天收到NUS来的一封信，in-principle approval letter for employmenet pass 其中里面有一段话是：Single Journey Visa This letter contains a pre-approved single-Journey Entry Visa for entry into Singapore. To use it, the pass holder should produce a copy of this letter to the Duty Officer at the immigration checkpoint. If it is uesd, a fee will be charged upon the extension of the Short Term Visit Pass Prior to collection of the Pass. 这是不是表明我可以不用去上海领事馆办理签证？不需要在我的护照上盖章，直接拿这封信的复印件就可以出境和入境了？ 我看网上有些人说只是准许入新加坡境，但是中国海关不会放行，所以还需要办理签证，是否真的这样？有没有人可以指点一下，多谢啦。
