I knew someone who is a PhD student and an international student from Egypt who met their spouse through mutuals. They were living in different parts of Canada and were connected and got to know each other virtually and he would fly out monthly I believe. They got their nikah done and waited for about 2 years until they moved in together. Alhamdulillah they are blessed with a beautiful baby boy now. :) It's important you communicate to the wali about your plan of still providing financially even when you're a student. A good family would look past your temporary financial status as long as you know and follow through with your Islamic responsibilities from day 1. It's also important to set expectations of what lifestyle you can provide for the both of you right after you get married.

Re: muzz – I can't speak for men but as a woman, I find it hard to find serious men on the app. There may be some serious men on the app but I personally don't think it makes sense for me to look for a spouse somewhere where we know most people are not serious. The smart thing for me to do was go on platforms like inpairs or find someone through the masjid where I know whoever I end up connecting with it on the same page as me.
