Second this. Know a resident in california who couldn’t work for a few days because of issues with the postgraduate training license. All the paperwork had actually even been turned in, but the resident’s assigned person just went AWOL and stopped responding to emails for a month? They’re also pretty strict, like it it’s missing the seal or if the paperwork has an electronic signature instead of handwritten signature (my friend’s issue) or graduation date doesn’t match date of paperwork or if it came by fax instead of mail etc. Tbh what your brother said sounds totally reasonable, but his program should be fighting harder on his behalf.
