How long will the visa file of Immigration New Zealand be kept?

The validity of the study visa depends on the payment of tuition and living expenses, that is, the actual study time in New Zealand is generally not more than 4 years. If you renew or transfer an immigrant to obtain a permanent residence visa, the old study visa will be invalidated and replaced by a renewed new visa or permanent residence visa.

In addition, there is no case that personal files, including visa resumes, are "destroyed" and will generally be permanently filed in the immigration office.
