It's really way too early to tell what the processing times will be in Sept 2021.
Because of Covid delays, we don't even know what the current October 2020 processing times are, let alone what they will be in 11 months' time.
The UKVI official processing standards times for spousal visas (UKVI's target times) are:
- 95% processed in 12 weeks (60 working days)
- 100% processed in 24 weeks (120 working days)
If you purchase the Settlement Priority Service (about $760), it should give a decision within 30 working days.
However, the processing times are subject to how many applications they have in the processing queue at the time you apply and whatever happens with Covid in the next few months.
Right before Covid, I think priority applications were taking about 20 working days, but in 2019, they were taking a lot longer.
Best thing to do is check back in maybe 8-10 months and see what the processing times are like then.
Another thought that I proposed was having a shorter honeymoon in America while my application is being approved, but I couldn't remember if my husband's passport would have to be sent away. He's unfortunately on assignment in Scotland until next September, so I am not looking forward to this year of separation!
If your husband is the UK citizen sponsor, then no, his passport will not need to be sent away. You just include a copy of the photo page of his passport for the application.
