我不太明白这句话“ He can file for Adjustment of Status at later date after Z as long as the visa bulletin remains current for filing and her green card has not been approve."
特别是这句话中的 "the visa bulletin remains current for filing". 比如，十月的绿卡排期（Filing date/表 B）到 2021年12月1号。 " the visa bulletin remains current for filing"是指十二月一号之前吗？
-Yes, but it changes every month. So, after he enters US using H-4 visa, you need to check the Visa Bulletin every month to see whether your I-140 prority date is still current for him to be qualified for filing I-485 just as you do for yourself to filing I-485 now.
