If you plan to visit the UK, you should get a visa. How do you apply for a British visa?
Your nearest British mission (British embassy, high commission or consulate) that offers an entry clearance service also provides application forms and information free of charge.
You will need to fill in a visa application form and give this to the visa section at a British embassy overseas together with the following documents: your valid passport or travel document a passport-sized (45mm x 35mm) color photograph of yourself. The photograph should be: taken against a light colored (white, off-white etc.) background; clear and of good quality; printed on normal photographic paper; full face without sunglasses; hat or other head covering unless for ethnic or religious reasons. The visa fee is usually payable in local currency.
What supporting documents should you include with the application?
The documents will depend on the type of visa you apply for. The guidance notes will give an indication, but there may be others that you should include. The documents that the visa sections around the world will ask for can vary and you should visit the visa section's website to find out more.
You could be asked for supporting documents. For example you will usually need to show that you have enough money to pay for your trip, and your food, accommodation and expenses in the UK. To prove this you can be asked to show bank statements, pay slips and evidence of savings - yours and/or your sponsor's, depending on who is paying the costs. Also you will usually need to show that you will leave the UK at the end of your proposed time there. To show this you could send evidence of your job, or continuing studies in your home country.
If you are not sure whether or not you should include a particular document, include it. It is better to have too many than not enough. But please do not include an excessive number - the entry clearance officer only has a limited amount of time to read the documents.
You should include original documents if possible, particularly those relating to birth, marriage, divorce and death. If you are not able to include originals of these then you should send attested copies. All original documents will be returned to you. You should not pay for any travel tickets until a decision has been made on your visa application, but you may want to send evidence that you have reserved flights.
Where do you apply?
You can apply for a visit visa or an EEA Family Permit at any visa section of local British embassy that offers a full service. To apply for the EEA Family Permit within the EEA, you will need to show that you are living legally in an EEA member state. For other types of visa you should apply in the country where you are normally and legally resident. Usually each British council or other mission has their own websites where you can find out more about visa section opening times, documents required, waiting times, etc.
The "Do I need a UK visa?" questionnaire on this website will tell you where your nearest British embassy offering an entry clearance service is, or any British mission can advise you where to apply.
