I agree with the others. You will have a hard time getting a job in Lithuania, even as a taxi driver. A better bet is to start your own company in Lithuania. If you do, you will be able to get a residency permit to live here. But you need to have the money to start the company and that is not cheap. As an example, there is a well known Indian guy who started a very successful Indian restaurant in Vilnius. There are a few others from India here, but not many.
If you have a permit to live in Lithuania, you can NOT travel to the UK without a visa. The UK is not part of the schengen agreement. However, if you have a permit for Lithuania, you can travel to most other European countries visa free.
