You can apply for an Online Student Visa in New Zealand anytime, as long as you meet the student visa requirements. But it does not mean you are guaranteed to receive a student visa. The statistics from August to September 2022 represent a rather challenging reality. Onshore and offshore applications recorded 38% and 24% of student applications were declined, respectively. Like other visa applications, you will need to present your persuasive argument on a cover letter that you are entitled to have the visa in light of relevant immigration instructions, accompanying strong evidence to back it up to the satisfaction of your case officer. If your student visa application is declined, you will lose the non-refundable tuition fee and any other costs. Your future visa application(s) is likely to be adversely affected as a result. That is why it is prudent to have professional legal representation from an immigration adviser licensed by the NZ government.
