1. Dear Elina, your mother can return and spend more time with you in the future so long as she does not exceed spending six months in any 12 month period in the UK. The multiple entry visitor visas allow one to travel to the United Kingdom for 6 months out of 12 months. One is only allowed to spend a maximum of 6 months out of 12 months in the UK. Once 6 months in the UK have passed, you will need to leave the UK for 6 months. The permit holder does not need to return to their home country, and are allowed to travel to any other country as long as they are outside the UK. The visitor visa is multiple entry, which means one do not need to travel and stay for the full 6 months in the UK. For example one can travel for 2 months to the UK and leave for 2 months, travel again for 2 months and leave for 2 month etc., as long as the permit holder does not stay in the UK for more than 6 months per 12 months. So, the five months last year will not prevent her spending six months in the UK this year.
