现在正在准备申请DES，但是在网上看到DES 的有效期不是从课程的截至日期算起，而是从申请的那天算，
请问这里有人申请过DES吗？你们的签证是从哪天算的？谢谢了。。。
从申请的那天算，但DES只能在课程截止日期前60天内提交申请，不能早也不能晚。
谢谢了，
哎，为什么不从课程结束那天算呢！
是的，从递交申请的那天算起。可惜了我的T4还有半年多…
我半年的t4 也将可惜掉:(
'Course end date specified on the CAS: when issuing the CAS to be used in the
Doctorate Extension Scheme application the sponsor must specify a course end date.
This should be the expected course end date agreed by the sponsor and migrant in
the weeks before the student completes the course, and may be different from the
course end date given on the original CAS. The student’s 12 months additional leave
will start from this date, so it is important that it is as accurate as possible. '----Home Office
