Summarize the following:
Look for work in Spain online prior to moving or in person once you’ve arrived or are there to visit. If you're from the U.S., you can stay in the country for 3 months without a special visa.  If you're from another country, you may need to apply for a travel visa. Check your local Spanish consulate to find out more. The job market in Spain is fairly competitive, so you must pick an industry that is need of workers. The retail and food industry is often in need of skilled workers. You can also find work teaching a foreign language, such as English, and technical jobs are also in demand. Because there are fierce regulations guiding employment of non-EU citizens, it may be difficult to find an employer who will sponsor you.  To see an up-to-date list of in-demand jobs in Spanish, check http://www.sepe.es/. This visa allows you to live as a long-term resident in Spain without citizenship. As long as you can prove you have the money to remain in Spain without employment, the country will usually allow you to renew it.  To stay in Spain under temporary residency, you must be able to sustain yourself. That means you either have enough money in the bank already to support yourself or that you are self-employed or independently wealthy.  You must show you have at least 25,560 Euros a year in income for the time you will be in Spain, as well as an extra 6,390 Euros for each person besides yourself. Keep in mind that these numbers can change over time. If you are a citizen of an EU country, you don't need a long-term visa to stay in Spain. You can live and work in Spain, as these countries have free movement agreements. This rule also applies to citizens from Iceland, Liechtenstein, Norway, and Switzerland. Add biographical information, information on your passport, your flight itinerary, and your current address. You will also need to add information on your Spanish address if you have one; if you don't, put in the city and region you plan to live in. The form will ask you questions about your family, your reason for entering, and the type of visa you're applying for.  You can obtain a form from your local consulate, which will help you figure out the best one to use. Otherwise, you can use this form in English with most English-based consulates: http://www.exteriores.gob.es/Consulados/NUEVAYORK/en/ServiciosConsulares/Documents/2010Solicitud%20de%20visado%20nacional%20-%20EN.pdf. You can also move to Spain with a student visa. This form is primarily in Spanish, but you can find directions on the second page. It's a short form that asks for basic biographical information, such as your address, email, marital status, and cell phone number. Find the form here: http://www.exteriores.gob.es/Consulados/HOUSTON/es/ServiciosConsulares/Documents/EX01.pdf. Always check with your consulate for the appropriate form, as it can change from time to time. You will need a passport that doesn't expire for at least a year, along with 2 passport-sized photos. You can get passport photos taken at most drugstores and some big-box stores. You can even take one yourself, but you should read up on the rules for passport photos, which include things like having no glare, not hiding your face, and using a neutral background. You can show you have this income through stock and investment statements, your bank account, or any other official paperwork. You will need to establish you have enough money already for the time you intend to stay in Spain or that you receive enough money to sustain yourself. This is a way to tell the Spanish Government why you would make a good resident. You can introduce yourself, your purpose, and establish the length of your stay.  For example, you might write something like, "It's been one of my life-long dreams to live in Spain. I've visited on multiple occasions, and I admire the people and the culture tremendously. I have always been a law-abiding citizen, and I love to volunteer and help locally whenever I can, which I will also do while living in your beautiful country." This is also a good place to discuss how you have the means to support yourself in Spain if you need to do so. You can even list what is in your bank accounts. "I also have the means to support myself while in your country, as evidenced by the steady income provided through my stock investments, listed below." Have your doctor write and sign a letter on official letterhead that states you do not have any contagious diseases. You must be examined by your doctor within the last 3 months first for this purpose. You must also establish you have international medical insurance while you're in Spain. This document shows you don't have a criminal record in the last 5 years. You can apply for one through your state's department of justice or through the US Department of Justice, FBI. In other countries, contact your local government. You will need to fill in a form, pay a small fee, and be fingerprinted for this process.  You can find a list of state websites for this purpose here: https://www.hcch.net/en/states/authorities/details3/?aid=353. This clearance must be within the last 3 months. This form also requires some basic biographical information. You'll need to mark the box for the appropriate visa. For instance, for a non-lucrative visa, check "Autorización inicial de residencia temporal," which tells them what visa you're applying for. If your documents are in another language, they need to be translated into Spanish.  Don't forget to make copies of all the documents for yourself. You will also need an original and a copy for the consulate. You will need to apply in person once you gather all of your forms and documents. Call your local consulate to make the appointment. They will help you with any problems with your application. Ask about the application fee before coming in and what form you need to bring it in.
