Do you have a spouse/parents/children in the UK? Those are very obvious links that you can show through marriage certificate, birth certificate, etc (but you'd also need to show they are living here i think, that's why I was suggesting sending something that proves that).
Ah I see - understood on the proof that the family is in the UK
So there would be some official records like that. But it feels somewhat... not enough to show
strong links. This may not be exactly an informed legal/rule-based opinion, but if someone where to show me a marriage certificate, I would not take it as evidence that they have a strong link to their spouse. Ditto for birth certificate for parent/child relationship, or most official records like that.
I would need more somehow. Say, photos together, records of holidays taken together (I guess better if in the UK in this case!), copies of messages sent, evidence of shared activities, evidence making plans and carrying them out, that sort of thing.
And that's just family in this case. For employment I would need something a bit more than payslips or a contract - something would need to say the applicant is emotionally invested to making their employment-related life in the UK. Ditto for "home in the UK" - I would need something more... emotional... than a mortgage or rental agreement. Not that these sort official records aren't important as evidence, but they feel not enough to me to convince the links are
strong
