我正在等母亲的延期审批，10月6号到期，听说按照现在延期审批的时间，想在I94到期之前拿到approval notice几乎是不可能，那么万一延期被拒了10年签证就有可能作废。
这种情况下大家一般是不再延期，过六个月再来呢？
还是说延期基本上都会批准，呆在这里等approval notice就好了？
如果让老妈回国算了，给老人搞一个十年签证不容易。可是签证批下来努力都白费了！
如果让老妈10月6号前离开美国去度假，等到签证下来再入境可以吗？会不会10月6号不在美国境内，相当于放弃了延期申请？
有人转了官方文件，如果被deny确实签证会作废。这是link：http://www.uscis.gov/sites/default/files/USCIS/Resources/C1en.pdf
If your application is denied, you may be required to cease
employment and depart the United States immediately.
In addition, any nonimmigrant visa in your passport granted in
connection with your classification becomes void. Once your visa is
void, you must submit any new visa application at a U.S. consulate
in your home country (not a third country, except in rare instances
as determined by the U.S. Department of State).
