My daughters Thai friend is getting ready to apply for a Tourist Visa to visit UK. What documents will she need to present with her application? Daughter is paying all her expenses and I will be traveling with her to UK, Bangkok /Heathrow and back, she will be staying with my family in England for 3 weeks then drive to Germany for 1 week staying with her sister then back to Heathrow to fly home.
TLDR : Answer Summary
To apply for a UK Tourist Visa, your daughter's Thai friend will need to provide several supporting documents to show her intention to return to Thailand after the visit. These may include an invitation letter from the sponsor (your daughter), proof of sponsor's financial capability (bank statements and income proof), proof of accommodation in the UK, relationship documentation (photos, letters), and evidence of ties to Thailand (such as property ownership or children). It is also important to note that she will need a separate Schengen visa for traveling to Germany.
