This question already has an answer here:
My mother-in-law is currently taking care of my borther's new born baby. We applied for a 2 year Standard Visitor visa, assuming she would be stay for 6 months at a time, with a month or two break in-between coming back to South Africa.
Upon entry in the UK, border control informed her the limitation is not per visit, but she would be able to return again within the same 12 month cycle. In other words, she would have to return back to South Africa for at least 6 months before she would be able to return again to the UK.
The page explaining the visa and it's purposes, is not very clear and open to interpretation, which is why we chose the 2 year Standard Visitor visa in the first place. All information and documentation supplied supports out initial intent as well.
Question: would she be allowed back in, considering the situation, without a 6 month break?
