Under the current rules, whoever comes to the UK as an investor must invest in a share or debt capital of UK companies within the next 3 months. Your arrival date (keep your ticket) is called the investor start date. It means that an investor visa holder has 3 months to prove their status.
If you cannot prove with your documents when you came to the UK, or if you switch to the UK investor visa from another visa type, the date of your application approval by the UK immigration authorities is taken as the starting point.
If 3 months are not enough to take an informed decision about investing in UK shares, we recommend seeking advice from experienced specialists at Imperial & Legal. Our advisers will help you to build both a safe and profitable investment portfolio.
