Anjaneyulu Pentyala is about to be deported, having spent $23,000 coming to New Zealand and simply says: "I don't know what to do."

He is part of a group of student visa-holders served deportation notices because their India-based agent used fake documents - he says they didn't know.

They paid 1,000,000 rupees to come here and study - that's $23,000.

Their one-year IT and business courses have just a week to go. There will be no refund.

Mr Pentyala says returning home will bring shame on their families.

"If I return, I can't see my parents' face. They feel bad, and I too feel very bad - how can I show my face to them?" he says.

"They trusted me, and they spent a lot of money on me. How can I go back - seriously - I can't go like this."

Newshub has revealed India-based agents overwhelmed New Zealand authorities with fraud.

"The agent has done the wrong thing. Why are they blaming us. We can't do anything," Mr Pentyala says.

"We didn't do anything wrong. Those bloody people have done everything."

Hundreds of students are here illegally, but only a few are being deported.
