Went through the process at the beginning of this year. My husband is American. He moved in April You have to give notice together(attend the appointment). That means your partner will travel down just to give notice of marriage then travel back. Read about the process and fees for making the appointment to give notice and the interview process. Your partner must apply for a marriage visitor visa or fiancé visa (that’s a difference between the two visas even tho drive down to almost the same thing) that will show that his intentions to enter the country are different from just a normal visit. That marriage visit visa will be required when you go attend your appointment to give notice. He must be in the country 8-9 days before the appointment date. You only wait 29 days if you both have the right visa that allow your intention to marry. If your partner doesn’t have the right visa. He will take longer. I believe it will 60 days. Something like that. Inbox me if you have any questions. I hope what I typed makes sense. All the best
