If you are moving to London there are a few matters that pertain to living abroad that need to be addressed before settling into life in London. Persons entering the United Kingdom are subject to conform with the immigration rules. Check with your local British Embassy, British High Commission or British Consulate for the latest conditions.
The official UK Government website carries a list of the addresses of most British Embassy addresses and phone numbers. You will also find detailed information about visa requirements, application, rules, helpful travel and health advice, and warnings about trouble-spots to avoid.
