Not sure where to find the data, but what are the trends in native-born vs. foreign-born Asian Americans through time?

Isn't the Asian American population still like high 50s % to 60s % -ish foreign born (first generation) now. If Asian immigration slowed down significantly, would we see the Asian American share become majority native born within a generation (or maybe the East Asian share -- right now only Japanese Americans are really statistically majority native born ones whose families are multi-generational stateside)? But then again, the Asian American native birth rate is not that high either.

The Hispanic/Latino American population is only in the 30-something % foreign born (down from near 40% in the turn of the millenium) and has more or less been mostly native-born now for a while, as the immigration leveled off. But the Hispanic native birth rate was pretty high for the previous generation. Now, more or less all the races in the US don't have that high of a birth rate, but closer to 2.0 children or less (black, white and Asians all below 2, Hispanics close to 2).
