The days of most expats having their children’s school fees paid for them are gone and even if you have an education allowance as part of your salary package it will stop on finishing secondary school. If they then want to go on to tertiary education, whether that is university, college, or vocational study someone has to pay and the burden is likely to fall on to parents.
Have you thought about how much may be required, or how to fund the additional study that you children may want, or indeed may need, in order to do what they want in life and be successful?
Statistics show that over their working life someone with a bachelor’s degree in the USA will earn, on average, almost twice as much as workers with a high school diploma. Source: US Census Bureau
