请问，我登陆快一年了，现在是在校生。以前也去过美国，现在想申请一个长期的美国签证，以旅游去签可以吗？另外我现在在Manitoba，是不是一定要去calgary签？可以递多伦多吗？
另外在要求提交的材料中写要“original landed immigrant paper”，是要交原件吗？另外还有"proof of social and economic ties to,and a permanent residence in a country outside of the U.S,such as proof of employment,source of financial support,documentation of close family relationship ,established business or profession, property holding, or other binding factors"这些是指哪些材料？还要交国内父母的资料吗？要的话又是指什么呢？
谢谢！ |
