There was nothing tough about the US Immigration paperwork with our circumstances. But the orchestration of the Danish residence and work visa, and all the revolvers import/export paperwork with the Danish govt and the US State Dept is the tough part. Very time sensitive. I ll be amazed if it all falls into place. As of now though, we are doing good and are right on track. Did I mention that the offer from Denmark is only good for six months?
If it were me, if the firearms was the holdup and my 6 month window was closing, I would leave them behind.
