签证申请的时间对于确保您的签证准时到达至关重要。美国国土安全部的公民和移民服务部政策是按照收到的顺序处理签证申请，但建议申请人在线检查他们的处理时间以保持最新状态。尽早开始申请流程，然后耐心等待。按照当地美国大使馆或领事馆官员的指示，保持沟通渠道畅通。如果你不理解某些事情，不要害怕提问。如果您认为需要移民律师，请咨询移民律师。提前至少15分钟到达面试，以便进行安全检查，并准备好所有文件。如果可能的话，用英语进行面试，穿得合适 – 就像面试一样。如果您申请临时非移民签证 – 例如旅游，学生或工作签证 – 等待通常在几周或几个月内进行。但如果你想永久地移居美国并申请移民签证，并最终希望获得绿卡，那么等待可能需要数年时间。政府根据国会配额和申请人的原籍国和个人资料等变量考虑申请人的案例和因素。国务院为临时访客提供在线帮助。如果您申请非移民签证，政府的在线估算师会让您了解世界各地大使馆和领事馆的面试预约等候时间。在咨询师批准您的申请后，该网站还将提供签证处理的典型等待时间。但是，有些情况需要额外的行政处理，根据个人情况显着增加等待时间，通常少于60天但有时更长。处理等待时间不包括通过快递或本地邮件将护照退回申请人所需的时间。国务院在紧急情况下授予加急面谈预约和处理。如遇紧急情况，请联系您所在国家的美国大使馆或领事馆。说明和程序因国家/地区而异。美国政府允许某些国家的国民在没有签证的情况下来美国工作或旅游长达90天。国会于1986年制定了免签证计划，以促进与世界各地美国盟友的商业和旅游关系。
The time of the visa application is critical to ensuring that your visa arrives on time. The US Department of Homeland’s Citizenship and Immigration Services policy is to process visa applications in the order they are received, but applicants are advised to check their processing time online to keep them current. Start the application process as early as possible and wait patiently. Keep communication channels open as directed by local US embassy or consulate officials. If you don’t understand something, don’t be afraid to ask questions. If you think you need an immigration attorney, please consult an immigration attorney. Get an interview at least 15 minutes in advance for a security check and prepare all the documents. If possible, interview in English and dress properly – just like an interview. If you apply for a temporary non-immigrant visa – such as a trip, student or work visa – waiting usually takes place within a few weeks or months. But if you want to permanently move to the US and apply for an immigrant visa, and ultimately want to get a green card, then waiting may take several years. The government considers the applicant’s case and factors based on the quota of the Congress and the applicant’s country of origin and personal data. The State Department provides online help for temporary visitors. If you apply for a non-immigrant visa, the government’s online estimator will let you know the waiting time for interview appointments at embassies and consulates around the world. After the consultant approves your application, the website will also provide a typical waiting time for visa processing. However, there are situations where additional administrative processing is required, and the waiting time is significantly increased depending on individual circumstances, usually less than 60 days but sometimes longer. Processing wait time does not include the time required to return the passport to the applicant via courier or local mail. The State Council granted an expedited interview appointment and handling in an emergency. In case of emergency, please contact the US Embassy or Consulate in your country. Instructions and procedures vary by country. The US government allows nationals of certain countries to work or travel in the United States for up to 90 days without a visa. Congress established a visa-free program in 1986 to promote business and tourism relationships with US allies around the world.
