I can confirm OP. USPS International Express Priority Mail (IEPM) is absolute garbage. Never use it ever. I sent an envelope of time sensitive documents to the Philippines that were needed for CRBA interview that was scheduled a month in advance. I've been told that that their 3-6 day promotion wasn't actually true (Hence the * next to the advertisements). The Post office routinely blames customs for this. Knowing this, I mailed on June 24, 2024 which needed to arrive before July 25. By July 1st the tracking still says the package has never left the original post office I handed the envelope to. I've spoken with USPS staff and they all tell me "No sir - we didn't lose your mail. Its still too early to be worried. We are confident everything is on its way" I also made phone calls regarding it to USPS customer service. Although they were very kind and understanding, all I could do was put in search requests and inquiries and wait patiently for response. Panicked by how little time remained, I created a new packet of documents identical to the first. Each packet contained Exemplified court documents, and over 25 notary stamps which cost 10$ each from a public notary. On top of shipping charges - each packet sets me back $350. I mailed the Second package on July 3rd taking time off from work to fill out documents, visit court house, and get notary to have a new packet prepared ASAP. Second envelope arrives in LA on the 7th. Sits there for two days. Leaves LA 9th. Ends up in Tokyo 2 days later. Sits there for a week. Then they put it on a ship to Manila which arrives 5 days later. They put it on a ship again from Manila to the destination city which arrives in 3 days later. Today my wife goes to their post office, asks about the envelope and they told her "Oh, its at the pier. It should be here at the post office sometime this week. Should be here by Wednesday and we can deliver it in a day or two. This will make us miss our appointment. Thankfully the staff there were understanding of our situation that they made special arrangements to search for the envelope at the pier and deliver today. So from July 3 to July 22. That's International Express Priority. Sitting in customs. And being put on ships. So much for being Priority and Express!! As for my first envelope? Its gone. USPS has been unable to locate it. To this day the tracking hasn't moved from the original post office. Although their customer service have been very kind to me over the phone, and very understanding, it doesn't get mail to the destination. They have declared it lost. Now i must go through a long process to get my shipping costs back and claim on the 100$ insurance - which I'm sure they'll fight tooth and nail to not pay out because the notary didn't give me a receipt. TLDR: OP is right. Never use USPS International Express Priority Mail. Its garbage, and 3-6 days is a blatant lie. More like 3-6 weeks. USPS has another option you can try. Global Express Guaranteed (GEG) Which is 2-3 days guaranteed or your money back. Might be alot better. Its twice as expensive and I guess FedEx does all the shipping anyway. More on reddit.com

I don't have any suggestions or advice to give as I'm in a shipping predicament myself with USPS and ISC Los Angeles. My package has been in transit for 38 days. I really wish you the best and that your packages get where they need to go. Just know you aren't alone!

I’ve had international shipments handled by USPS and DHL and sometimes they say in transit then boom it’s delivered without even updating the tracking. So maybe there is hope you’ll get it sooner More on reddit.com
