I thought they made experiments on kids who recently moved in another country that show that IQ isn't stable in kids and depends on the environment?

There are environmental effects. Common sense things can affect performance on IQ tests, including taking the test a second time in short succession (you get better with practice). Certain early childhood education interventions will cause children to over-perform on IQ tests relative to their IQ measured later in life. If the subject has the flu, they will also tend to underperform. The environment definitely plays a role, but the degree to which it is stable is, to me at least, surprising.
