UK Visitor visa stay duration and rule to re-enter UK after 6 months

[nagsimigration2022]

Hello All,
I have a specific question about UK visitor visa rule for stay and re-enter UK minimum period (cooling -off period if any).

My mom already visited UK 2 times in the past with 6 months visa. Now, I am planning to get 2 years / 5 years visa for my mom to enter UK. Since this time it will be 2 years / 5 years with multi entry visa, I have this question.

Can my mon stay for 6 months (180 days) and she leave UK for a day or few days (assume, she can travel to EU countries). Can she re-enter UK after few days from the day she left UK and stay for another 6 months?

Is it possible? Is there any specific rule applicable on this case?

Thanks for your help

The Immigration Rules does not have any fixed guidance on the amount of time that a person can stay in the UK on a visit visa, apart from the limit of 180 days for any single visit.

However, it expressly forbids residing in the UK in the guise of frequent or successive visits.

(Section 4.2)...the applicant...(b) will not live in the UK for extended periods through frequent or successive visits, or make the UK their main home

The Immigration Officer can cancel a visit visa on the spot if in their estimation the visitor is attempting to reside in the UK as mentioned above. And such a cancellation can lead effectively to a life-long ban on visiting the UK

The expectation of a visit visa is that a visit is short and sweet. A single 180 day visit itself can ring alarm bells and the visitor can expect questioning on the reasons for such a long visit at the border the next time they try re-entering the UK.

The visitor is expected to have resided longer in their country of habitual residence than in the UK. Indeed, they will have been required to demonstrate a stronger connection to that country than to the UK, as a part of the visit visa application. If your mother only goes to EU countries rather than her country of habitual residence (which would be visible on her passport), questions can be raised as to precisely how strong is her connection to her country of habitual residence when she reapplies for a UK visit visa.

The purpose of a 2 or a 5 year visit visa is that the visitor does not have to keep filing new applications each time they wish to visit the UK. It is not for the visitor to have long stays in the UK.
