Red Tape and Visas
Visa is a identity of people so if any non visa citizen who stay longer than three months are officially supposed to apply for a residence permit for which you'll have to show proof of among other things a regular income or sufficient funds to support yourself during your stay.A visa is not necessary for UK citizens for short stays or business visits up to 90 days. Visas are required for longer stays and for any gainful activity. Applications can be made at any Czech embassy or consulate. EU passports are rarely stamped, however, so there is no evidence of how long you've been in the country.
