Cons:
some countries can have harsh conditions, you pay a lot of money that may be very expensive, citizens might not have a lot of freedom, other countries can have child labor, and illegal weaponry, many areas would have poor people
Pros:
You'll have a different culture, children would have education, people would speak in a different language, most countries have child labor laws (going against child labor) a nice economy, and very great tourists attractions (London, Paris, China)
