留学生可以先读社区大学再往上走：只能选SEVP认证学校，录取后拿I-20、全日制每学期至少12学分
美国国土安全部的留学生官方指南 Study in the States 写明，F-1 国际学生的高等教育选项包括社区大学、本科和研究生项目。也就是说，先在社区大学读两年、再转入大学完成学位，是规则内的正路，不是绕道。
第一步是选对学校。只有经过学生和交流访问者项目（SEVP）认证的学校才能招收国际学生，指南提醒学生用官网的 School Search 工具按校名、地点、教育类型或签证类型核对认证状态，别只听中介的说法。国务院的 EducationUSA 在全球有400多个咨询中心，也可以免费咨询各类项目的差别和助学金信息。
被录取后，学校的指定校方代表（DSO）会发 I-20 表格，这是整个留学流程里要收好的核心文件。之后先缴 I-901 SEVIS 费，再去美国使领馆申请 F-1 签证；入境最早不能早于 I-20 上项目开始日期的30天，随身带好 I-20、签证、护照、录取信和财力证明，走人工通道时要出示。
入学后维持身份的底线是读满全日制课量：在学院或大学读本科的 F-1 学生，每学期至少修12个学分；跟不上课业要先找 DSO 商量减课或延期，不要自己先退课。配偶和子女可以申请随行，但也要各自拿到 I-20 并遵守相应规则。（来源：美国国土安全部）
Community College Is a Real Starting Point for F-1 Students: SEVP-Certified Schools Only, an I-20 After Admission, and 12 Credit Hours a Term
The Department of Homeland Security's Study in the States guide states plainly that postsecondary options for F-1 international students include community colleges as well as undergraduate and graduate programs. Starting at a community college and moving up is a path inside the rules, not a detour around them.
The first step is choosing the right school. Only schools certified by the Student and Exchange Visitor Program (SEVP) can accept international students, and the guide directs students to verify certification with the official School Search tool, searchable by school name, location, education or visa type. The State Department's EducationUSA network, with more than 400 advising centers worldwide, can also explain program types and financial aid.
Once a student is accepted, the school's designated school official (DSO) issues the Form I-20, the core document of the whole process. The student then pays the I-901 SEVIS fee, applies for an F-1 visa at a U.S. embassy or consulate, and may enter the United States up to 30 days before the program start date on the I-20, carrying the I-20, visa, passport, acceptance letter and evidence of financial support in hand luggage for the port of entry.
After arrival, status rests on a full course of study. F-1 undergraduate students at a college or university must take at least 12 credit hours per term, and students who are struggling should talk to their DSO about a reduced course load or a program extension before dropping classes. Spouses and children may accompany the student, but they need their own Form I-20 and must follow the dependent rules. (Source: U.S. Department of Homeland Security)
