Normally it depends upon the country where you want to migrate and the visa type you are applying, for a few countries it is not a mandatory requirement to show the settlement funds. There are many countries which have it as a mandatory requirement as they basically want to know whether the applicant is aware of the cost of living and have sufficient funds to survive in the new country without depending upon the Government. This is again a basic requirement for a few countries where the visa type is specific to the state or region or the visa is being sponsored by the state or region.
