謝謝8老師，請教這個問題，我和愛人都是加拿大護照，但是二個小孩還是中國護照，不知道要不要提前辦理那種十年多次往返的美國簽證，還是等 我拿到TN簽證了，再給他們辦理TD簽證。謝謝
-Your child can apply for B2 or TD visa, but they had better apply for TD visa in the US Consulate in China or in Canada after you or your spouse become a TN holder because TD status allows them to stay in US much longer than B2.
