The introduction of the bond is racist as it only applies to black people.
The introduction of the bond will divide families at important occasions such as weddings and birthday parties as well as funerals etc. The introduction of the bond will be more harmful to those poor families who can not afford to put down the bond.
In cases where more than one person want to apply to come to the UK -- for weddings and funeral etc-- £15000 to £20000 may be required for cash bonds, that
is extremely unfair on those would be sponsors as well as the visitors.
