This process is long
there will be time when you dont hear from them for months. Don't stress. They will contact you if they have any concerns. The won't just refuse the application. They will endo you abd tell you that they have concerns or want more proof that the marriage is real. But they won't just refuse you. Don't worry. It's too soon
in about a month or so, you will get an email saying that you have been approved to sponsor abd then they will likely do the medical abd then transfer your file to the visa office that will continue the process. Sponsorship takes approximately 12 months.
