You can accelerate 5-10 years to 3 months using pay for citizenship schemes. For example Grenada has one where you get citizenship and a passport in return for "donating" $150k USD to the government. Grenada's is interesting because you get visa-free access to China. Antigua and Barbuda are running a "50% off sale" (I kid you not..) where the cost is only $100k USD (normally $200k USD)
