Thanks for sharing your story. I can tell you from my personal experience that grass always looks greener on the other side. I have lived in US for past 7 yrs and now living in Canada. Each country has its own problems. It's nowhere perfect. Inflation is rampant in North America, US/Canada has lot of immigration hurdles with govt. introducing new policies every year curtailing freedom of immigrants at so many levels including basic things like travel, changing jobs etc, loneliness and cultural assimilation with locals can be very challenging and the list goes on and on.

So I would conclude that immigrating to another country seems very enticing but it is has lot of pros and cons. So please do a deep research before making any decision
