请问F1已过期可以在加拿大或墨西哥renew 吗

目前人在美国(STEM OPT). 签证已过期，手上有一个到年底过期的加拿大旅游签证。想去加拿大renew F1.但看到官网说"Nonimmigrants who are already in the United States, have an expired visa, and remain in legal status are encouraged to apply for a new visa at non-border U.S. Embassies "。不知道是啥意思，想知道F1过期的情况到底可不可以去加拿大或墨西哥renew?感谢回答!
