I am a UK citizen. My registered partner, of 5 years, she is Hungarian. We've been together for 16 years. Before Brexit, we used to come and go to Hungary. Since Brexit (we've both turned 60), we would like to spend more time with my partner's elderly Mother (she's 90) in Hungary more than the 90/180 day rule allows. Is there a solution for staying longer in our case i.e. can I get some kind of visa/residence card to allow me to stay for longer periods? Thanks.
