回複：請問關於AP紙的問題

1。一張AP紙是否隻能用一次？
--Usually for multiple use before it expires, unless you applied it for one time use.

2。在現有AP紙到期前能否申請並使用新的AP？（現有AP紙已用完,且距其失效日還有半年，這期間想回國一趟。）
--Yes, you can apply a new one and use it. But if your AP is still valid, why do you need to apply a new one? What do you mean for "AP紙已用完"?

多謝！
--you are welcome
