Pretty sure there's no legal requirement for asylum seekers to fill in paperwork before they enter a country. Could be wrong though.
Well I don't know about this, but they generally need to do more than turn up at ports undocumented.

Offering people a free ferry ride is pretty dangerous I guess yeah. Good point.
Wait, you mean just go and pick everyone up from Calais? Blimey. I thought you meant escort them in, pick them up off the boats. My apologies. I didn't realise you were actually talking about just going to Calais and saying "who wants a free ferry ride to the UK?"
