She has been on a couple of extra trips without the others. Since Brexit there is a limit for how how many days a year UK citizens can spend in Shengen area countries without getting a full visa, just like all other non EU citizens. If Mia had exceeded that number or was close to it, that might be why she had to go to Gibraltar (a UK overseas Territory) as you risk fines or even prison if you overstay.Is Mia’s visa taking longer because she has a different last name and needs permission from her birth dad or anything like that? I thought if she were to have her birth dad’s last name, it would be a lot more difficult to get a visa seeing as she needs her birth dad’s permission as well? Might be wrong though.
