My friend requires some travel advice. He has traveled quite a bit and over the years acquired many different visas to many different countries. The truth is that on most of his Visa applications including to the UK and USA he has told many significant untruth such as 6.3 Have you ever been refused a visa for any country, including the UK? and also used false documents the most recent being sometime last year.
He will be applying for a UK visa this month. Should he proactively confess to these previous transgressions or continue in them since they have never been discovered? Is there some waiver of penalties if one proactively comes forward? What are the consequences of doing so? References will be helpful.
