An important distinction separates residence and citizenship. The permit allows you to live locally, typically subject to renewal, but citizenship normally requires a long period of residence. Any offer of a passport in return apartments for sale in biarritz an apartment purchase is reason for caution.
Past the headline threshold, these schemes impose further conditions. Frequent requirements include proof of no criminal record, medical insurance, proof of income and a minimum stay on local soil annually. Ignoring any of these can end the residency regardless of the property.
