我现在刚从F1转成H1B身份，有I-797和I-94，从来没申过H1B签证。我护照上有一张未
过期的F1签证（到今年12月）及I-94，查了travel版FAQ及美国移民局网站，去加拿大
的visa auto revalidation指的是护照上有H1B过期签证才适用。
想问下我这种情况还能从加拿大返回美国吗？
补充：我想开车入境

自己查了下Travel版的详解，貌似是可以的：
该条规定同样适用于在美国转过身份，即护照上的过期签证和现在身份不符的情形。比
如原签证是F-1，后来在美国境内转成H-1B，虽然护照上的失效签证为F-1，而现在身份
为H-1B，仍然可以利用上述条例，从加拿大或墨西哥返回。
某校International Center的解释：
The automatic revalidation will also work for someone who originally entered
the U.S. in one non-immigrant status (such as F1) and has since changed to
another non-immigrant status (such as H1B). The expired F1 visa will be
considered to be revalidated and changed to H1B for the entry from Canada or
Mexico. Those in H1B status should also carry the original I-797 approval
notice while traveling which you can borrow from the ISSO.
