Following the rule change in 2015, third party support can be offered by anyone anywhere in the world. The rules covering this are published in Appendix V, Paragraph 4.3.
The fallacy applicants frequently entertain is that the use of a third party substantially elevates the quality of an application. It doesn’t, it has the reverse effect. Much of the time, the Entry Clearance Officer will accept that the third party has the capacity for support and take it as a given. But the applicant’s circumstances, ties to their country, and lifestyle are too weak and so the application is refused.
Financial support is not the major element in a visa application. Instead the big gorilla in the room is Paragraph 4.2 (a) + (c)…
- (a) will leave the UK at the end of their visit
- (c) is genuinely seeking entry for a purpose that is permitted by the visitor routes (these are listed in Appendices 3, 4 and 5)
…and these have nothing at all to do with third party support.
Depending on the ECO’s determination and if the third party is resident in the UK, they may ask for an Sponsorship Undertaking. If the ECO decides an undertaking is needed (and this is an extremely rare event), they will contact the applicant and ask for it. It’s part of standard advice that this form should not be submitted unless asked for, and that a consultation with a legal professional should be obtained prior to submission. Submitting the form as part of the applicant’s original evidence may cause it to be ignored.
obiter dictum: terminology-wise, UKVI likes to use the term “third party” in the rules instead of “co-sponsor”, but the terms are fundamentally equivalent.
