내용으로 봐서는 다른 회사에 취직하신 후 다시 그 회사가 I-140를 내면 될

행운을 빕니다.

Getting I-140 approved does not change the applicant’s non-immigrant status. Applicant is still on the same non-immigrant status before I-140 was approved.

An I-140 petition approval is entirely contingent upon the employee remaining in the same job. If the job changes, then a new I-140 is required. This is true whether the I-140 is sponsored or self petitioned, though in the case of a self-petitioned I-140, a new job that is substantially similar would continue the validity of the petition.
