父母拿了一个多年多次往返签证，但是每半年要求处境一次。所以想着最方便的方法是去美国处境一次，在回来，就又有半年的期限了。但是在美国大使馆的网站上，看到好像这样的情况拒签率很高。想要问问有没有前辈们得经验，如果肯定不行的话，就不想浪费钱和时间了。原文如下：
Important Notice for Applicants with a Visitor's Permit to Canada
With rare exceptions, visa applicants temporarily visiting Canada should apply at the U.S. Consular Section in their country of residence. If the applicant is not a resident of Canada, interviewing officers at the U.S. Consular Sections in Canada may not have experience in evaluating the circumstances in the applicant's country of residence. The applicant will, therefore, have greater difficulty establishing eligibility for a U.S. visa in Canada than would be experienced in the applicant's home country.
A substantial percentage of visitors to Canada are denied visas under these circumstances. Consequently, we strongly urge visitors to Canada to apply for U.S. visas in their country of residence.
谢谢
