Hey guys... I sent my package to Chicago on 8/17/2015. Today I don't get a receipt notice yet. What should I do now? Thanks.

Hi Aleksandra, I found out that I missed some tax documents of my sponsor. I think I need to wait two more week to get receipt :(.

Thanks for your help. I will let you know asap.

Should I email the lockbox support to ask about my case?

The tracking said that it was delivered on wednesday August 19. The agent helped me file this. I believed they sent the cashier's check. How...

I sent it as a PM 2 day and it also contains tracking number. I sent from San Jose, CA.

No, I didn't get any letter from them.
