我的extension approval date 是 11/17/2011。而我是12/17/2011 持舊H1b入境的 (10/10/2012到期)。
-It is very confusing. You have been working for the same employer, haven't you? If so, how could you file the H1 extention in advance about one year (before 11/17/2011) before your old H1 approval expires (on 10/10/2012)? The H1 extension only can be filed in advance up to 6 months before the old H1 expires based on immigration law.
