If all else fails, a good way to attain liberty while still being able to follow and support the liberty movement in New Hampshire is to become a "PT" which stands for "Perpetual Traveler", "Prior Taxpayer", "Permanent Tourist" and other such creative and related terms as "Passing Through".

Now this isn't exactly an immigration tip, but could be the solution you're looking for if you are having trouble getting a legal permanent residence or citizenship yet do not wish to get stuck in your own country with the possibly growing threats to your life, liberty or property. Becoming a perpetual traveler means that you would be able to legally stay in NH for up to 3 months at each visit in that time socializing and cooperating with fellow free staters. A B1/B2 (regular visitor for pleasure or business) visa would do, and if you arrange your PT strategy to include citizenship in one of the countries participating in the visa waiver program you might even be able to visit without a visa.

When you're not in NH you are in another country of your choice, also as a tourist, and you can alternate your stay between other countries and New Hampshire. You could probably, for example, arrange your traveling/tourism life so that you alternate between only two countries, NH and some other country of your choice. This way you could be in NH for three months possibly two times every year. You could time your visits so you can participate in NH liberty events like the Porcfest or the NH Liberty Forum.

Probably best strategy would be to start with a visit to NH for three months and see if there's any way you could turn your stay there into permanent legal residence. If not then you could flip to the PT strategy as the backup plan. In either case you change your life and become much freer compared to where you were.

There is a lot more to being a PT, however, which can liberate you from high taxes and regulation of greedy Big Governments. You can find more about that on http://sovereignlife.com, ran by a libertarian. It is an excellent resource.

Good luck.
