> ...but I do know that he's being held to a much higher standard than almost anyone else because of his race.Your measuring stick is 90% blank. How you measure "higher standard" are table stakes in the Ivies.
csa already did a good job explaining this which apparently didn't sway you, so I'm going to try a different tack.
If you ever get the opportunity to meet in person face to face in an intimate setting with Bill Clinton, Barack Obama or Arnold Schwarzenegger, I encourage you to avail yourself, and observe as detached as you can. The change in the room is palpable and electric. Their charisma is off the charts powerful.
I'm familiar with Clinton's charisma, and it is stunning to watch at work. It isn't just his extraordinarily comprehensive recall, but also how he deploys it. You can observe the mechanics, like warmly restarting a thread of conversation with someone he last met a few years ago as if he simply turned around from another party guest a few seconds ago. But even among top politicians who employ the same technique, he stands out in the refined fashion with which he delivers it.
Think how many people regularly in your life have that kind of charisma. The Ivies still reject candidates with that level of magnetic personality because they lack in other dimensions.
By using the metrics you use, you are limiting your son and yourself. Those metrics come with a hard ceiling. Where the Ivies are going, there are no ceilings, there are no metrics in the first place. World class admissions means being open to von Neumann-scale, I-didn't-believe-that-possible possibilities to surprise the admissions committee and delight in that.
You don't achieve that surprise and delight with what you have mentioned so far.
Your son sounds like a terrific human being and you are rightfully fiercely proud of him and what you have accomplished as a parent and successful immigrant. Keep pushing forward on that trajectory, for college is not the pinnacle, just another foothill towards that summit reached at the end of our life. He can (and I'm sure will) still achieve incredible heights in his life, Ivy or not, as long as he continues to improve himself and the little part of the universe around him that he can personally make better. Successful dents in the universe have rarely historically come stamped with Ivy diplomas, and I wish someday to read about a dent your son makes and delight in my surprise at where that dent shows up.
