Also, a lot of the land here is part of a volcano called el Tiede. So, most people live in a very narrow strip around the outside of the island. I'm back after a little break to do some sightseeing and some work. I would like to share with you the details of a trip I had to take some time ago. A visa is something that is added to your passport so that you can enter a country.
Different visas have different rules.
For example, my visa here in Spain says that I am only allowed to stay in the country so long as I am working at the Instituto de Astrofisica de Canarias, and that I'm not allowed to have a job anywhere else. Other types of visas may let you enter a country to find a job, to be a tourist, or to seek safety. One of the requirements of my visa is that I had to register with the local authorities here on Tenerife. That way the government of Spain can keep track of the various foreigners in its country. To help me register with the authorities, my friend Monica offered to translate for me.
