Obviously I can come in and out of UK as I have done so in the last 7 years. I have entered UK for multiple times and my longest stay was a month. I and my partner would like to get married and since we want to do it right by abiding immigration rules, we are looking at marriage visitor visa since I don’t plan to stay in UK. My question is, I have two children who are US citizens, do I apply for them? If so, in what type of visa? They will be coming with me for the wedding and I’m not sure if they can just enter the UK like how we have been doing without a visa requirement. Thanks in advance!
