谢谢863211的解答，但是我女儿是做与专业有关的校外暑期工作，不是学校要求做的。学校说现在用掉的OPT时间从毕业后的OPT时间中扣除。我查了CPT的解释，好像不适合她。“Curricular practical training is defined to be alternative work/study, internship, cooperative education, or any other type of required internship or practicum that is offered by sponsoring employers through cooperative agreements with the school."
