避免排期的两大方法

1，Cross-Chargeability
你的配偶的出生地点和你是不同国家/地区且无cut-off date或是cut-off date比你晚。

If a national of a country with very early cut-off dates has a spouse who was born in a country with later cut-off dates (or no cut-off dates), then AOS applications can be filed simultaneously for both individuals under the principle of “Cross-Chargeability," which would charge both visa numbers against the yearly quota of the spouse’s country of birth.

2，Retention of Priority Date
如果你申请了几个140，你可以保持/利用PD早的那个140的PD(前提是PD早的140尚未被据也未被撤回)。

Current USCIS regulations allow an individual for whom an I-140 immigrant petition has been approved to retain the priority date granted to that petition for any subsequently filed immigrant petition, as long as the earlier earlier petition has not been denied, revoked, or withdrawn. Please note, however, that a priority date granted to one individual’s green card application cannot be transferred to another individual. Individuals in the process of filing new PERM AEC application can also retain an earlier priority date accorded to a pending traditional or Reduction in Recruitment AEC application, as long as the new PERM application is for an “identical” job opportunity.
