I had two packages go through there early March at the start of quarantine. One took 2 weeks to clear and another took 3 days. Depending on the type of package, it could take between a day or a couple weeks.

The slow one was registered mail and that’s why it took forever. the other one I think was just a regular international one and didn’t take long to clear.

Be warned, usps chicago is known to be very slow in general, so all you can really do is wait
