485提交后不到180天可以跳槽吗？

请问下大家，485提交后不到180天跳槽有什么风险吗？需要重走perm吗？到新公司后是不是可以等到180天以后再file J表？

我的理解是：Perm要重新走。在老公司提交485的180天以后才可以file J表。

必须pending 180 天才可以port到新雇主，否责要重排PERM

详细见：https://www.uscis.gov/policy-manual/volume-7-part-e-chapter-5

要点如下：
1. General Portability Requirements
To qualify for portability under INA 204(j), the adjustment applicant must meet the following eligibility requirements:

The applicant is the beneficiary of an approved Form I-140 petition or of a pending petition that is ultimately approved;

The petition is filed in the employment-based 1st, 2nd, or 3rd preference category;[4]

The applicant’s properly filed adjustment application has been pending with USCIS for 180 days or more at the time USCIS receives the request to port;[5]

The new job offer through which the applicant seeks to adjust status is in the same or similar occupational classification as the job specified in the petition; and

The applicant submitted a request to port. If the applicant makes a request to port on or after January 17, 2017, the applicant must submit a Confirmation of Bona Fide Job Offer or Request for Job Portability Under INA Section 204(j) (Form I-485 Supplement J). If the applicant requested to port before January 17, 2017, the applicant could have requested to port through a letter, since Form I-485 Supplement J did not go into effect until January 17, 2017.

交485满180天跳槽，也适用于按表 B 交485的情况么？
另外，485满180天是从哪一天开始算？ RD 还是其他 date？

应该交上485就算吧，不管是A表还是B表算的
从RD开始算，这个相当于USCIS confirm收到申请的时间
