分享个STEM Extension申请的corner case处理办法给和我情况类似的同学

由于跳槽的时间节点的原因，和当时的雇主先签订了I-983，然后用I-983申请了STEM I-20。但是我没有寄出I-765，因为onsite之后觉得有9成把握拿到offer，而且学校OIS强烈不建议changing employer while application is pending with USCIS. 所以我没有提交申请给USCIS，但是我已经在4月1号收到STEM I-20 based on former employer.
拿到offer后，和旧公司敲定5月3号last day，新公司5月20号才入职。于是联系L家的HR，要求提前file I-983 before start date。HR欣然允诺，然后BAL马上initiate process，现在等待I-983中。所以我的情况总结一下就是，有基于旧公司的STEM I-20，但是没有file I765，现在需要拿着新东家的I983申请新的I-20，然后file I-765。这是个属于比较corner的case，所以打电话咨询了学校OIS的advisor，和大家分享一下她建议的流程。这个流程是基于USC OIS，其他学校的同学可以参考一下，心里有个底。

In order to receive a new STEM I-20 with your new employer, please complete the following steps:
1.      Update your new employer information in the SEVP Portal
2.      Email OPTSTEM@usc.edu with the following information and PDF documents attached:
o   Your full name
o   Your SEVIS ID Number
o   An explanation of your situation, including confirmation that you did not mail the STEM  application to USCIS
o   Photocopy of your previously issued STEM I-20
o   New eShipGlobal shipment request with the order number included
o   Completed I-983 for your new employer
o   Screenshot of your SEVP Portal that shows your new employer information
o   Completed Change of Employer form: https://ois.usc.edu/files/2019/0 ... T-Extension-COE.pdf
