However, if you do that, the period of time that you are permitted to stay will depend on the immigration rules to the United Kingdom. There are actually several rules for people who would like to operate in the uk and stay here for 90 days or more. If you meet these criteria, however, it'll be easier for you to obtain your own visa and work here legally.
