签证什么的职业填什么？
1.你的情况，如果申请美国大学，属于国际学生(international student)的范畴了; 如果申请社区学院，还是属于非移民身份； 如果是申请美国高中（包括寄宿高中和私立走读中学），也是属于非移民身份。 请按照你目前的情况填写职业那一栏！ 2.关于美国的签证类型，其实大致就是三大类：
非移民签证 Nonimmigrant visa ： 顾名思义，就是不改变你在美国的法律地位的非移民状态; 非移民签证又分为很多种：
F-1 and M-1 visa for academic and vocational students， J-1 Visa for exchange visitors (visitors coming to the U.S. for a short period of time to study， teach or assist in an internationally sponsored program)， H-1B， L-1， O-1， P-1， Q-1 visas for professionals from other countries， TN status for Canadian and Mexicans working as professionals等等。 移民签证 Immigrant Visa： 这是改变你在美国身份的合法途径之一， 有两种：
EB-5 for foreign nationals who invest $500K into a commercial enterprise that creates at least 10 full-time jobs with a minimum investment of $400，000 for targeted employment areas， EB-2 and EB-3 for those whose professional occupations require "specialized knowledge" or are "professionals，" etc.
Diversity Visa Program： this is also called the Green Card Lottery， since it results in receiving green cards， not permanent residency. The Diversity Visa program brings 50，000 immigrants every year to the United States through a lottery system where all people around the world have equal chance of winning provided they were born in an eligible country which has never sent more than 5，000 immigrant visa applicants during the previous five years to the US. This includes China， India等亚洲国家以及非洲地区。
