再重申一遍,这是我们学校国际学生办公室的官方faq
你看了就知道了!
Can I work for more than one employer?
Yes. You can work anywhere that applies to your major and as long as you
submit an OPT Employment Update for each position.
How many hours per week can/must I work?
To qualify as being employed, you must work at least 20 hours per week.
There is no maximum to the number of hours you can work.
Can I volunteer to stop the 90-day clock?
Yes. You may work as a volunteer or unpaid intern while on OPT where it
does not violate labor laws. Check with the HR office at the company or a
labor lawyer to verify this. The volunteer work must be at least 20 hours
per week. You must still obtain a letter from your supervisor for the
volunteer position to verify that you are not being paid and that you are
volunteering at least 20 hours per week.
Do I have to submit an OPT Employment Update for a volunteer position?
If you are ONLY volunteering and the position meets the criteria mentioned
above, yes. If you have a primary position and are doing something for, say
, the Red Cross in your free time, no.
How do I renew my driver's license?
You need your OPT I-20 and EAD to do this. If you don't yet have your EAD,
you can request a letter from ISSS and take that along with your OPT I-20 to
the DMV along with their other required documents.
