There is never a guarantee with anything and unfortunately, in this type of forum, we cannot provide you with any assurances.
What I can tell you is that your husband will not be able to return to the U.S. with you immediately after your wedding. As the spouse of a U.S. citizen (the U.s. does recognize marriages in foreign countries as long as they are considered valid there), your husband will need to have an immigrant visa before the U.S. will allow him in to live with you on a permanent basis. An immigrant visa entails a two step process - filing an I-130 with USCIS and then having the foreign national apply with the State Department in the home country for the visa. This entire process can take about a year and a half. The other choice is to try for a K-3 visa, but this also takes about a year or so to complete the process. Your husband won't be able to come back with you without either of these types of visas.
If you don't go over to get married, you can try to then bring him here as a fiance with a K-1 visa. That also takes about a year with the slow processing times that are happening right now.
Unfortunately, there is no easy solution to the problem. He cannot come here as a nonimmigrant (temporary) because he has a U.s. citizen spouse with whom he wants to live on a permanent basis. The immigration authoriteis do not allow people to use temporary visas, which are much quicker to obtain, as methods of entry just to then turn around and file green card paperwork.
