It is very important that the broker works not only with US citizens, but also foreigners and tries to fully provide all technical support to foreign users.
A little history about Interactive Brokers. This broker has been working in the US market since the late 70s. For all the time of its work, the broker has established itself as a reliable, advanced in information technology partner.
