Re refugees. I found an article in the Scotsman archive >from 1st April
1939, about Czech refugees the British government tried to turn back at
Croydon Airport, South London (some were sent back, some allowed to stay).
It seems ;-
1) you had to be sponsored by a Refugee Committee to be allowed to stay,
2) prove you already had relations in this country who could vouch for you,
3) prove you had enough money to live independently.Or
4) you had to prove you were on your way elsewhere eg. USA.
