My wife and I, both UK nationals living in UK, are inviting my wife's widowed sister to visit UK at our expense.
We will provide a letter of sponsorship to her sister to support her application for a Standarrd Visit Visa.
Apart from pledging financial support and attaching signed copies of our UK passports, what other 'evidence' would the VFS agency in Bangkok require?
Clearly, with the current time taken to process visa applications, it is not sensible to book a return flight yet, from what I can glean from viewing the UK Govt Visa Application
site, they are asking for travel dates.
Any pointers willl be appreciated.
