大家好，我在填DS-160时有个问题让我有点不安
Do you have any specialized skills or training, such as firearms,
explosives, nuclear, biological, or chemical experience?
我选YES
描述写
When I was a graduate and undergraduate student, I majored in chemistry.
20XX-20XX In Prof. XX's lab, I studied in material science.
20XX-20XX In Prof. 00's lab, I studied in bioinorganic chemistry.
英文写很烂我知道，因为当时想赶下午五点前去邮局缴费，结果没赶上
想请问一下
这样是不是踩到敏感的雷会吃红单?
我DS-160还没付钱，跑出条码跟邮局缴费单，但是 SEVIS已经付钱了(200镁)
这样还要重新写吗
还是会留下纪录，早晚领红单?
