Answer:
If Hawaii gained its independence from the United States, its inhabitants would go through a series of major changes, namely:
-They would stop being American citizens to become citizens of Hawaii.
-They would be considered foreigners by the United States, so their residency and immigration status should be reviewed (unless treaties were signed between nations regulating this issue).
-Hawaii would lose the investment of the federal government, with which the economy of the nation would be impacted.
-For its territorial isolation, Hawaii would lose great connectivity with the world, since most of the flights that arrive at its airport do so through stops in mainland America.
