第一次安排的宣誓日期是4/23號，因為5/10要回國看九十歲老母親，考慮到申請美國護照來不及，就申請reschedule, 打電話老是轉不到人工，後來通過online chat申請了reschedule, 但4/24號狀態更新，說是no appearance, 寄出來一份信，需要按信上說的做，這份信我一直沒收到，5/9號狀態又更新了，說是reschedule了，我於5/10去了中國，5/16號收到通知，新的宣誓日期是5/21，我5/19號聯係移民局要求reschedule, 5/20號收到通知不能reschedule, 當時已經沒法趕回5/21號的宣誓，於是寫了個詳細的解釋以及要求reschdule，發給老公，老公打印出來，寄給移民局，現在我人返美，我還能再做什麽？
我的綠卡6月底到期，我需要先renew 綠卡嗎？
-Not have to (not need to waste your money to do it).
我現在是加拿大護照。
ChatGPT 說可以再打電話給移民局，和in-person appointment, 你能不能給我點建議我該怎麽辦？
-Normally if you missed the oath ceremony twice without reasonable explanation, then your N-400 probably will be revoked. Because you requested reschedule of the oath ceremony with explanation, I think you should be fine. You need to contact USCIS to reschedule the oath ceremony appointment by phone (talk to a live person on phone and ask him/her for suggestion in your case). If possible and necessary, ask USCIS to make an appointment for you to visit the USCIS Field Office near you.
