It might depend on the type of benefits, I'm not sure. They have a backlog that's for sure.
I applied for retirement benefits in August last year, (November eligibility), had my interview in mid October, sent all required documents in late October and silence ever since.
I'm about to embark on the ID.me process (separate thread) so I can view my own On-line SS account (& IRS account), which hopefully will give me an up to date status.
