以上是小編推薦赴美簽證邀請函模板的內容，簽證通常是附載於申請人所持的護照或其他國際旅行證件上。在特殊情況下，憑有效護照或其他國際旅行證件可做在另紙上。隨着科技的進步，有些國家已經開始簽發電子簽證與生物簽證，大大增強了簽證的防僞功能。簽證在一國查控入出境人員、保護國土安全、防止非法移民與犯罪分子等方面發揮了重要作用。護照是持有者的國籍與身份證明，簽證則是主權國家准許外國公民或者本國公民出入境或者經過國境的許可證明。簽證一般都簽註在護照上，也有的簽註在代替護照的其他旅行證件上，有的還頒發另紙簽證。如美國和加拿大的移民簽證是一張A4大的紙張，新加坡對外國人也發一種另紙簽證，簽證一般來說須與護照同時使用，方有效力。
