Well, Jason, spirituality aside, unfortunately Scotland's borders are not open to US citizens who feel compelled to move over. You need a visa to do a/thing besides visit here. You've got several options:
- Work permit - find an employer willing to sponsor a work visa for either you or your wife.
- HSMP visa
- Student visa - apply to enter university and the student can work part-time; spouse can work full-time.
Sorry, but it's just not a matter of feeling compelled to move here, so you up and do it. If that were the case, half the country's population would be American. You'll have to get a visa before you can settle here. Best of luck to you.
