"non-immigration visa" is H1B; 什麽情況下會有“all the I-94s being changed/exdended status"?, I-94 不是在入境時才會有嗎？
-For example, if you enter US on May 1 using H1 visa, but your H1 approval notice/I-94 will expire in August 1, and thus, you need to extend your H1 again and then, you will get the new H1 I-94 when the H1 extension is approved, and so on.
