Having relocated from Denmark to Costa del Sol in Spain about three years ago, I can offer a perspective that might be useful here — though I want to be honest: truly "pro-migration" countries in the long-term structural sense are harder to find than the rhetoric suggests.

That said, based on my own experience and conversations with fellow expats across Europe and beyond, here are some thoughts:

**Spain — and Andalucía specifically** — has been remarkably welcoming in practice. The Non-Lucrative Visa, the Digital Nomad Visa (introduced in 2023), and the Golden Visa program show a government that is actively trying to attract foreign residents and entrepreneurs. The local culture in the South is genuinely warm and integrative — I've met Moroccans, British, Dutch, Scandinavians, and South Americans who have built real lives here over decades. The bureaucracy can be frustrating, but the underlying social attitude toward immigrants is positive. In a country with an aging population and declining rural areas, immigration is seen as economically necessary — and that sentiment tends to be durable.

**Portugal** often gets mentioned alongside Spain for similar reasons — NHR tax regime, D7 visa, active courting of remote workers and retirees. Lisbon and the Algarve are very international. The political consensus around welcoming immigrants has been stronger historically than in many EU peers, though recent elections have shifted things somewhat.

**Canada** remains structurally one of the most pro-immigration nations on earth — it's baked into national identity and economic policy. Points-based systems, Provincial Nominee Programs, and pathways to citizenship are well-established. The challenge is cost of living and housing, which has become severe in Toronto and Vancouver. But for a business owner with a niche engineering firm, the Atlantic provinces or smaller cities could be very viable.

**New Zealand and Australia** are also worth considering if you're open to that part of the world — skills-based immigration, stable political systems, and genuine cultural pluralism.

For someone running a precision engineering company with operations in both Europe and the US, I'd actually argue Spain (or Portugal) makes strong strategic sense: central timezone, EU market access, educated workforce, and — crucially — a political culture where immigration is not a hot-button wedge issue in the same way it has become in Germany, France, or the UK.

The key variable you flagged — long-term political stability on immigration — is hard to guarantee anywhere right now. But countries where immigration fills a structural economic need (aging population, labor shortages, depopulation of regions) tend to maintain pro-immigration policies regardless of which party is in power. Spain fits that profile well.

Happy to share more on the practicalities of relocating a business to southern Spain if that's of interest.
