我今年是要到美国念PhD的新生
学校发给我的I-20是给加拿大护照的
SEVIS线上也完成缴费
以下是我在网站上找到入境所需资料的资讯
https://ca.usembassy.gov/visas/canadian-students/
1. A Canadian passport;
2. The original I-20 (or DS-2019) certificate;
3. Proof that the SEVIS fee has been paid;
4. Proof of ability to pay school fees and living expenses in the United States;
5. Proof of ties to Canada.
我的困惑是第五项Proof of ties to Canada到底是什么
我大部分的时间都待在台湾生活
是有一些亲戚在加拿大
请问有人有相关经验吗?
