Remember if you are a visa national you will require a visa to enter the United Kingdom. You will need to complete an application form. Applications, except those for asylum and work permits or under EC law, will not be valid unless they are made on the appropriate application form. You are free to transact business in the United Kingdom either as a tourist or in connection with your employment or business overseas. You may not: take paid or unpaid employment either for someone else or on your own account; produce goods or provide services within the United Kingdom; or sell goods and services to members of the public. You may: attend meetings with United Kingdom businesses or negotiate and enter into contracts with them; and attend trade fairs, conferences and classroom training.
