不少人遇到这样的情况，手里的大签（学签或工签）以及护照上的小签（入境签证）仍然有效，可是由于护照过期，需要换发护照。那么过期护照内贴有的尚未过期的小签还能用吗？

EZCAN 移民专家张丹权威解答，能用。

护照过期不影响护照内仍然valid的visa有效性。尽管护照过期，但是签证持有者仍然能继续使用过期护照内尚未过期的签证，直至签证到期。入境时只需要将新旧两本护照和旧护照内仍未过期的签证一同呈交边境官查看即可。尽管移民条例规定，签证的签发有效日期通常不会超过护照的有效日期，但是现实中确实存在有效签证贴在过期护照上的情况。

由于贴在旧护照上的签证无法被挪到新护照上，所以如果希望签证贴在新护照上，那么就需要提交replacement申请并缴交政府费用。如果希望新护照上的签证有效期长一些，那么就需要提交新的签证申请，而之前旧护照上的签证也就随之被注销了。

官方原文：If an expired passport contains a valid visa counterfoil, the counterfoil can still be used since the expiration of the passport has no effect on the visa's validity. Holders of a valid visa may continue to use their visa until the date it expires even if the visa is in an expired passport. Visitors can fulfil the visa and passport requirements by presenting both the renewed and expired passports containing the valid visa counterfoil to a BSO when seeking entry into Canada. The Regulations state that visas should not be issued longer than the validity of the passport. However, due to pre-IRPA cases, it is possible to encounter visas in expired passports.
