Mine took also almost five months but still received it last week.I really don’t know what’s going , it’s been four months since my employer applied for my endorsement letter and I still haven’t gotten a response as yet.
the last up date I got was that the required and updated signature for this year . I did that, and I’m still waiting . Next month is going to be 5 months since my application was sent in .
As hard as it is, I’m sure you‘ll receive it soon aswell.
