请教美国留学~打工

我想问一个问题，你朋友的工作是“INTERNSHIP (实习）” 或者“CO-OP"之类的关于他的专业的工作吗？

美国的留学生，特别是F-1学生是比较难找工作的，H-1的学生情况好一点。美国现在很严格，所以一般的工作只留给绿卡持有者（美国永久公民）和美国公民。你的朋友可能是通过学校的CAREER DEVELOPMENT CENTER 找 INTERNSHIP/CO-OP,他工作的公司帮他办理工人卡号码 （SOCIAL SECURITY NUMBER，在这里有了工作就有这可以申请社会保障号--很重要的一样东西，有了以后才能积累信用记录，并便于找以后的工作）。

你的计划都不错，不过要注意的是，如果没有学校的帮助，找到的工作一般是很低微的工作（比如餐馆的杂工BUSBOY)，待遇很差，随时有生命危险。所以你要三思啊。不要为了一张绿卡而失去学业或者其他更重要的东西。

下面的资料是我COPY过来的，不知道对你有没有用。
校外工作许可：OPT、CPT

CPT- (Curricular Practical Training)
1. the F-1 student must have been “lawfully enrolled” as a full-time
student for at least one full academic year. Thus, if a student arrives in
August and spend fall and spring at WPI, they can do a CPT the summer after
their 1st year. If they arrive in January, they do not qualify for CPT until the
end of the following winter after they have completed one spring and one
fall semester.
2. The training must be “an integral part of an established curriculum,”
directly related to the student’s field of study and commensurate with the
student’s education level
3. The training may be full-time or part-time. If full-time (more than 20
hours per week) for 12 months or more, the student is not eligible for
Optional Practical Training (see below).
4. CPT employment authorization is duration, employer, and locationspecific.
At WPI undergraduates are eligible for 12-week summer co-op
internships validated by the Career Development Center, and graduate
students are eligible for summer internships for graduate credit with the
consensus of their advisor. Authorization paperwork is coordinated through
the International House.
5. A job offer is required to complete CPT paperwork

OPT- (Optional Practical Training)
1. The F-1 student must have been “lawfully enrolled” as a full-time
student for at least one full academic year.
2. Time spent in an off-campus program (at WPI- IQP/MQP/HUA
programs) during a student’s course of study can be counted towards the
one academic year requirement, as long as the student had previously
studied for one year in F-1 status in the US prior to engaging in the offcampus
program
3. The completed OPT EAD application must be received by USCIS prior to
the completion of study, and so students must begin the process early
enough to allow the International Student Advisor at WPI to update SEVIS and
generate a new I-20, and to ensure the completed I-765 is received by
USCIS.
4. The training must be directly related to the student’s field of study and
commensurate with the student’s educational level
5. The most common OPT is “post-completion” meaning a student begins
the full time work upon completion of their degree
6. No job offer is required to apply for OPT, although students need to find
employment within 90 days of the start date of their OPT in order to “stay in
status.”
7. The training is limited to a maximum of 12 months, per degree level,
although students in STEM fields (science, technology, engineering or math)
are eligible for a one-time 17 month extension of their OPT.

可行是可行 但是不是那么容易申请
最关键的是 你来美国为了什么？打工？ 好多在美国被迫打工的人 都是没见过市面的 每小时8块在餐馆就干 一个月累得半死挣个2000美金 自己还以为不错呢 不知道美国但凡一个中产阶级年薪也要5万多 所以在这个国度 知识就是力量 单靠打工 是不可能有出息的。
另外听您的意思是想黑在这里混绿卡 而不是留学为主打工为辅 这种情况不建议 有太多的例子最后没有拿到身份 而且还耽误很多年时光。如果真的打算这样干 就必须做好生活艰苦的准备（那真的是艰苦） 准备好很多年不回国 甚至10年20年不见亲人一面 找一个专门的律师事务所 每个月给他门钱 才有可能办理这种情况的身份。
