"This was when we did 'Inconquistable Corazón' that I had to relocate here."

Con la crisis económico, me tuve que radicar en España.
"Given the economic crisis, I had to relocate to Spain."

Radicarse en otro pais es dificil.

El problema radica en la falta de presupuesto para este sector.
"The problem lies in the lack of budget for this area."
