legal or not legal??

high school and college??

Legal, as long as the ball is across the plane onto the court.

Straight from the NFHS book.

9-2-10 THROW-IN PROVISIONS
. . . The opponent(s) of the thrower shall not have any part of his/her
person through the inbounds side of the throw-in boundary-line plane until the ball has been released on a throw-in pass.
NOTE: The thrower may penetrate the plane provided he/she does not touch the inbounds area before the ball is released on the throw-in pass. The opponent in this situation may legally touch or grasp the ball.

The NCAA ruling is the same.

A.R. 103. Team A has been awarded a throw-in after a violation. A1, during
the throw-in, breaks the boundary plane with the ball and
extends the ball over the playing court. B1 causes a held ball.
The possession arrow favors Team A.
RULING: A1’s breaking the boundary plane and extending the ball
over the playing court does not violate throw-in provisions. B1 legally
grabbed a live ball and caused a held ball. The ball shall be awarded to
Team A for an alternating-possession procedure.
(Rule 4-37 and 6-3.1.a)

A.R. 150. Thrower-in A1 breaks the plane of the boundary line by
extending the ball over the playing court during an alternatingpossession
procedure. B1 creates a held ball. The official awards
the ball to Team A since the alternating possession for the
throw-in did not end. Was the official correct?
RULING: The official was correct. An alternating-possession
throw-in ends when the throw-in ends or when the throw-in team
violates provisions of the throw-in. A1 has five seconds to release the
throw-in. The throw-in count shall end when the ball is released by
the thrower-in so that the ball goes directly into the playing court.
The throw-in shall end when a passed ball touches or legally touches
an inbounds player or when a player, who is on the playing court,
touches and causes the ball to be out of bounds, or when a throw-in
provision has been violated. Breaking the boundary plane with the
ball by extending the ball over the playing court is not a violation of
the throw-in provisions but the act does cause the ball to come into
play.
(Rule 6-3.2 and 4-67.4 and .5)

A.R. 240. After a field goal by B1 with two minutes left to play:
(1) B2 reaches through the end-line plane and slaps the ball from
the hands of A1 or touches the ball as it is passed along the end
line after the score; or
(2) After a warning, B2 prevents the ball from being promptly put
in play by slapping the ball away.
RULING: In both plays, a player/substitute technical foul shall be
charged to B2 for delaying the game. This act shall also receive a
warning if one has not been previously issued for reaching through the
boundary.
When A1, in making the throw-in, extends the ball through the end-line
plane into the playing court and B1 slaps the ball from the hands of A1,
without B1 breaking the plane above the end line, B1 has not committed
a violation because the ball is in play once it crosses the end line.
(Rule 10-3.8 and 10-3.11)
