This is correct. US Citizens can open an account with an overseas broker if they are not a resident of the US (living abroad). US based traders can't. Each broker has their own rules regarding banks and other details, but the main rule is based on country of residency. If the OP is not based in the US than it's possible he can open an account with Dukascopy.
DislikedAs a US citizen i can open a dukascopy account if I can prove I am not resident in the US. Other brokers do not allow me to open an account even if I am not resident in the US. One american broker will not allow me to open an account if I am using a Canadian bank account.
It is a real mess.Ignored
