American checks

Hello Expats, I went today to open a new bank account with Banco Pichincha, I asked the personal banker if they accept American checks to be deposited to the same person’s account. The answer was yes and it will take one month to clear the check. The fees for a deposited check of amount of $4000 would be $250 dollars.

Are there any expats who heard that before or were able to deposit American checks recently paying high fees?

Thank you
