今年五月拿了EAD卡，明年五月到期（一年有效）。但我有TN 后年才过期，现在用TN工作。想请教各位大佬EAD明年到期之前不延到后年TN到期之前再延期EAD会否因一年内未续EAD导至EAD失效不可再续了还是EAD可随时续。
-You can apply for a new EAD any time. But you had better renew it to have a valid EAD all the time in case you travel outside US using AP, which will make your TN invalid (you have to have AP to travel).
