This story is based on an interview with Erin Vlack, 48, a pharmaceutical supply chain consultant living in Valencia, Spain. It has been edited for length and clarity.

In April last year, two months after leaving my steady job in pharmaceuticals, I was in discussion with another company about a full-time position.

It was tempting to accept the senior directorship they offered, but I dismissed the idea at the last minute.

My 25-year-old son, Gavin, was studying medicine in Spain, and I missed him so much. "What if I moved to Europe to be with him?" I asked myself.

I spoke to immigration lawyers

I reached out to immigration lawyers that very afternoon. I'm a great believer in striking when the iron is hot, before excuses creep in.
