hello! I'm not sure if you have ever posted about this, but do you have an information on getting visas to go to the UK? (if you have could you so kindly link me to the post)
Are we talking work visas, school visas, or extended stay visas?
I’m not the most knowledgeable about this stuff to be completely honest. If you’re just looking to stay for a few weeks for travel purposes then I believe a passport would be sufficient, but I’m probably wrong. If you have access to a travel agency then I’d go pop in and ask them some questions; or, if they’re too far away, you could always try calling and/or emailing them?
