Any ideas over there Kenneth?managed to grow
Here's one... NGO Church and Religious based organizations sponsor many immigrating people.
Figure how to contact a few such groups in a region of the USA that is similar to where you are used to living, e.g. if it is rural small farms and that is where you can be immediately effective. From that start, then any trading expertise will be icing on the cake for both you and them, see what I mean vern? Whether you mention your trading ambitions may or may not be a plus to them, so act accordingly at least until you can show what you KNOW, not just what you think might be so.
They may be able to facilitate processes that can pull you into that situation and into the land of plenty while you also look into ways to push your way in. These things take time. How much is up to you. Tempus Fugit Kenneth.
