是加州大學2021年12月的本科生畢業生， 在申請OPT。
收到學校國際生辦公室辦OPT的I-20在學校通過。 誤以為是學校國際生辦公室30天以內繼續把申請遞交給USCIS。
剛發現是學生本人30天內遞交給USCIS這個OPT申請以及申請OPT用的I-20.
已經錯過30天的application window。F-1已經失效， 這樣也非法居留了1個月18天。
怎麽辦？
1. 必須馬上離境嗎？
-Because your school (Univ of California) has extended your I-20 for OPT (i.e., requested OPT in SEVIS for you), you may ask the International Student Office to see whether your SEVIS ID is still valid. If yes, you may apply for a new program or Master/Doctoral Program, then do the F-1 transfer within US. If your SEVIS ID is not valid, then you can apply for a new program or Master/Doctoral Program and get a new I-20. Then, go to Canada or China to get the F-1 visa to come back.
2. 可以留在美國境內為這個OPT情況上訴嗎？-No. 特別是最近疫情期間馬上回國基本不可能。
3. 需生有加拿大的旅遊簽證，好像可以在加拿大待180天。
-Then, you need to come to Canada as soon as possible.
4. 以後申請上了美國的碩士或者博士研究生，辦美國簽證回因為這個非法居留收到阻礙？
-Normally no if you leave US very soon e.g., within one to two months. But if you stay in US illegally for more than 6 months or one year, you will be subjected to 6-month or 10-year bar
您有任何的建議， 請告知。
