Same happened to me last year. Applied for tourist visa for Thai national to visit the UK. Gave all evidence, bank statements (hers and mine), gave them proof i have rented my condo here for 4 years, I have my own house and cars in the UK all paid for, provided proof my friend hss lived with me for 3 years in Thailand, has her own car and land and enough money to cover the trip. I even said I would cover alm costs and showed my bank statements proving i er 1 million UKP in my bank so no worries with money. Her application was reviewed in Delhi and declined siting they didn't believe we'd even met despite proof of traveling all over Thailand and Vietnam and living together for 3 years.π³π³π³ No possible appeal but can reapply. I was livid but mainly due to it being processed in India where they let thier families in all the time.....π€¬π€¬π€¬
