我父母去年９月來美探親，B２簽證今年３月初過期。我今年２月幫他們申請B２延期，後來由於疫情，到７月底才打了指紋, 然後我父母於８月底回國了。大概１１月多的時候又收到信，又讓我父親１２月１０號去打指紋，我當時還覺得奇怪，心想早就打過指紋了，而且人都回國了，就沒管它。結果今天又收到信，說我父親的延期申請被拒絕了，理由是７月底那次打的指紋不合格，讓他１２月１０號再去打指紋，他沒去。還說記錄顯示他８月底已經離境。說＂you failed to appear for the scheduled biometric services appointment. Additionally, there is no evidence in the record to indicate that, prior to the appointment time, USCIS received a change of address or rescheduling request justifying your failure to appear. Therefore, your application is considered abandoned and USCIS denies your request＂。 請問，我該怎麽辦？
-It is very normal. The denial will not affect anything because your parents left US duirng the extension case pending (i.e. before the case was denied). But your parents had better keep the I-539 Receipt Notice for the B2 extension filing, and also keep the air plane boarding card and the entry stamp into China in their passport. Then, bring these evidences with them in their future reentry to US.
另外，我母親的延期前幾天批準了。他們同時７月底打指紋，結果我母親指紋合格，我父親的指紋不"satisfactory", 造成後麵這一係列後果。
