對於I-407, USCIS 會寄receipt notice嗎？我父母三月份材料寄出後，沒有收到任何東西。所以想問有沒有查詢的途徑？再次感謝

-Normally they do not send you the receipt notice because the case process takes very less time to be approved. If you want to inquire the case status, you may send the inquiry by mail to the USCIS Lockbox where your I-407 was filed.
