It's not mandatory to do the changes immediately you can do it at your own pace as our governments around the world are slow when it comes to updating documents but yeah and affidavit is a legal statement you are making which is binding on you its like a contract where you declare something.
For example our affidavit we have mentioned that here on from the date of the affidavit we identify as either male or female or transgender and we change our name from given name to chosen name and we will henceforth use that everywhere for all official and legal proceedings
