About New Zealand.

One question, are your friend's two sisters biological? If there is, you can immigrate for family reunion. Because you can't get the government's living allowance, housing allowance, unemployment allowance and other benefits within two years after you get New Zealand immigration status through family reunion, you must have a skill to find a suitable job in New Zealand. Learning to cook now is to prepare for finding a job in New Zealand. If they lose their livelihood, the government will ask their sponsor (she is the doctor's eldest sister) to pay for their family's living expenses or cancel their immigration status.

Of course, it's easy to find a job as a chef in China in New Zealand. However, except for experienced chefs in better restaurants, other salaries are not high, generally around 500 New Zealand dollars a week. I can only support my family. At this time, another person needs to learn English well before going out to work.

Now their age is not a problem, because they are family immigrants and are not limited by age. However, her husband was over 55 when he obtained immigration status, so he was not eligible for a New Zealand pension in the future.

After obtaining New Zealand immigration status, high school education is free. College tuition is about 30,000 RMB per year. Plus the living expenses when his family can't find a job, and the agency fee, I think 600 thousand will be all.

As for the cost of immigration, it is different. There is a difference of hundreds of thousands between doing it yourself and looking for an intermediary.
