I’m a Customs Officer and we see human remains come across the border from
time to time. All you need to do is fill out the proper paperwork, in this
case, a 7523.
But if you try and smuggle in anything that is restricted or prohibited,
you’re in trouble. You have to declare everything. For example, if you want
to bring in more than $10,000.00 you have to declare it, fill out a simple
form, and be on your way. If you fail to declare it, we seize it. Even if
it’s a million bucks you won while gambling down in Mexico.
Hope that helps.
