IG 04/30 最终更新，无receipt

4/30/19 UPDATE: No receipts came in today’s mail (which is typical for a Tuesday). Last night at 11:29 pm, I received a premium processing email notification for an Advanced Degree petition filed at the California Service Center. I have not received any others since.

IG周二收到的一直比较低，应该是USPS的问题。
