I should probably reply to that.
The funds that you are describing are what we ask from any applicant who does not have a sponsorship of some kind in order to make sure they will have enough money to support themselves for that year. If they have relatives, if there is no undertaking of any type that would force that individual to help the new migrant, we have to ensure that the new migrant starts with the financial capacity in order to settle. Even if they have family members, there is no undertaking of any shape that is signed with us. We cannot have a guarantee that they'll have support when they're here.
That's basically the rationale.
