你顾虑和解决方法是对的。OPT可以是自愿。同时恭喜你拿到Intel的Offer.
What if I never find a job or never work while on OPT, am I “illegal”?
Students on the first 12 month of post-completion OPT authorization may not be unemployed more than 90 days total; students authorized for an additional 17 month extension may not be unemployed more than 120 days during the total 29 month OPT period. Your employment may be either paid or unpaid, as long as it is in your field of study and at least 20 hours per week. Immigration has not yet clarified the consequences of exceeding the unemployment limits, but it may include loss of immigration status or ineligibility for future immigration benefits.
