@batman It's actually great when these people come to London because they really take time to meet agents like me (we're not a lot in the UK) and catch up with what's happening in the immigration side of things.
With your comment about migrants staying in NT once they establish themselves there, you would hope that will be the case but it's not always and NT is wary of that so kailangan talaga yung applicant should cover every possible doubt that NT would have on the application.
