Great times all around

I live down in La Linea de la Concepcion, which is a very unique international community connected to Gibraltar (UK).
I have personally recommended RVF International to ALL of my teacher friends looking to live abroad and explore options for a new livelihood.
RVF has made the transition from US life to Spain life very simple and smooth, especially considering Spanish bureaucracy can be a NIGHTMARE for the uninitiated.
It's definitely worth the price to allow a third-party contractor to ease the navigation of law and services.
For your own self care, definitely be in the process of practicing Spanish (Castellano), but remember it's a diverse country so your language might not match theirs (especially in Andalucia). It's no shame to find yourself in a native language community, find some friends from your country, and have a good group of support even if your plan is "full immersion": the exhaustion from just starting life anew can be A LOT to handle, not to add language on top of.

Spanish people are incredibly loving and communal, so feel inclined to embrace the culture, as many people are happy to share, and appreciate YOUR appreciation of all they call home.
