My son is on a two year student visa in UK and would like to stay longer. Both my parents are dutch. My mum is not naturalised but my father is. My mother moved to NZ in 1955 and dad came over at about 1950. I was born in NZ in 1965. So my question is: Can my son get a dutch year visa either through his grand parents or even through me having dutch parents. My son is also born in NZ 1992.
