Not sure about the Mexicans, but the Chinese can get honest jobs in the U.S.A.
In California some Chinese even own their own agricultural farms.
It is very rare to see an Asian homeless person in the U.S.A.
Them running away to the very distant state of Maine to perform their illegal activities there appears strange, unless you factor in the heavy presence of the Mexican organized crime in California. I guess they are moving so far to avoid the Mexicans.
What other reason is there? There are extremely few Chinese in Maine, but, at the same time, there are also very few Mexicans.
