…is that a yes?

This feels like such a dumb question, I apologize in advance.

I (American) applied for a fiancé visa to go live with my partner (UK citizen) in the UK on December 27. I got a text on January 19 that my application had been processed. Neither the email or text said what the decision was, and logging back into my application didn’t provide any information. Today I got my passport back in the mail. No information was provided other than my returned checklists, but I have a sticker in my passport that says “UK entry clearance” for marriage/CP, valid until July 25.

…That’s an official yes, right? Or do I need to wait for anything else?

If that is a yes, for those about to apply, I did not pay for priority, and that happened a lot quicker than I expected it to.

Thank you all for your help, we appreciate you tremendously!
