My wife's parents and siblings are planning to visit my family in the UK. We are all Indonesians by nationality. They need to apply for family visitor visas, and one of the documents I need to supply them is an invitation letter.
- What do I need to specify in this invitation letter?
- Do I need to write one letter for each visitor or can it be combined?
- Who should sign the letter? Is it I, my wife, or both of us?
