I have a UK visitor visa of 5 years valid till March 2018. I am visiting UK every year for 20-25 days.
Now, I am planning to invest in a business of my friend in the UK. For the same I plan to apply for a entrepreneur visa. But before that I need to make some visits to decide for the same before I apply and invest. For this do I need to change my Tourist Visa to Business visa? Please note that the tourist visa is still valid upto Mar2018.
I fear if I make frequent visits, I may be stopped/refused at the airport. Last year, I was advised by the immigration officer at the airport to change my visa to business when I made two consecutive visits in a month.
