Don’t ever let anybody make you feel less as an immigrant. Even the rich Brits immigrate too. It’s a very natural behavior to look for better opportunities and explore them. You’ve not done anything abnormal. Whites immigrate. Blacks immigrate. It’s how the world works.
Let me ask a serious question. If you have $30-$40k saved up right, are you telling me your going to wanna put all that down on a house down payment just to have a $3200 mortgage??
