Providing the required information / documentation to support your application in a timely manner is key.
This information should be accurate, valid (if time limits apply, e.g. proof of ID and proof of residential address must be dated within the last 90 days) and clearly legible.
Most delays are caused by incomplete or incorrect information provision.
We recommend you:
Provide all requested documents together rather than one by one and in a PDF format where possible
Respond to additional queries in a timely manner, should the Acquiring Bank request additional information your application will be paused until this query has been satisfied
