签证申请的邀请函及担保人信息有何目的与格式要求？

An invitation letter and host information reassure the US embassy or consulate that your visit is temporary, you have a place to stay, and your plans are clearly defined. They are commonly requested for B1/B2 visa applications when you have a host in the United States.

具体细节

• 邀请函的目的是提供有关担保人、访客及行程原因的详细信息，确认申请人将进行短期停留并有井然有序的计划。
• 它说明访客将拜访谁、住在哪里、行程日期，并核实访问的临时性质。
• 担保人信息必须包括担保人的全名、地址、电话号码、电子邮件以及在美国的移民身份（如美国公民或绿卡持有者）。
• 信中的访客信息必须列出申请人与其护照上一致的全名、与担保人的关系、访问目的（旅游、商务或两者兼有）以及计划的抵达和离开日期。
• 信件必须由担保人签署，并正式致函您将前往申请的领事馆的美国总领事。
• 将其发送给签证申请人，以便他们在提交申请时出示；可选地，其中可包含访客的护照号码。
• 对于涉及比赛或特定商务活动的商务签证，可能还需提供公司出具的单独信函。
