I have twist on this question. My two children (girl 11 & boy 15) have inherited approximately $3,700 each from their Chinese grandmother in Wuhan. Last summer their aunt asked if I wanted to take the cash back. I was afraid of dealing with $7,500 so I declined. Are children allowed to take this much cash back to the US?

I should mention there are weird logistics here in that my children spend 6 weeks in Wuhan with their aunt and uncle and return by themselves through the airline's unaccompanied minor program. Also, apparently the money is in some kind of certificate of deposit where they only have a week or so window to withdraw the money -- otherwise, it is reinvested in something I am thinking is like a CD. Depending on the timing and the circumstance, I am thinking that maybe myself and my son (very mature) could each take $3,700 back at the appropriate time.
