You will likely need supporting documents every time you authenticate and legalize a document. This of course will depend on the type of document and the rules of the embassy or consulate. Each submission of a document for legalization will need to include the specific supporting documents, which are usually kept by the embassy or consulate.
We have clients who must produce the same type of document on an annual basis and they do need to provide the supporting documents every year.
Our expert staff can assist you with the supporting document requirements specific to your situation. Contact us today! Call us toll-free at 1-888-433-1011 or send us an online enquiry.
