The next step is to have the notarised copies or originals authenticated by the FCO. Many people think the authentication is of the document itself but, technically, they are authenticating the Public Notary’s signature or the document that the government has issued. For instance, the FCO may authenticate the a criminal background check, signifying it’s a legitimate document that can be used for your Z visa application.
Documents can be couriered to the Legalization Office of the FCO (here is the official website) and can be returned via courier. The FCO charges £30. Unfortunately, they do not offer discounts for multiple documents.
Courier costs range between £5.50 and £25, depending on where you are (the UK, EU or Rest of the World). If you are in the UK, you can can opt for snail-mail. Although the risk of your precious documents going AWOL for just a few pounds’ saving, may not be worth it’s while.
Once the FCO has the documents, the process takes about 10 working days.
