Moving to the United States from Spain is a life-changing decision that involves far more than simply changing address. It is a process with a series of emotional, logistical and legal challenges that need to be considered carefully. From adapting to a new culture to handling bureaucratic procedures, every step calls for meticulous planning.
One of the main hurdles is obtaining the right paperwork, such as visas and residence permits. These procedures tend to be complex and require a clear understanding of the legal requirements in both Spain and the United States. The need to translate official documents into English adds a further layer of complexity.
The language barrier and cultural differences can also be significant challenges. Adapting to a new environment, building support networks and understanding social and workplace norms are all crucial to a successful transition. That is why it is essential to prepare properly and to have the support you need to make this change of life easier.
Essential paperwork and procedures for moving to the US
To settle legally in the United States, you must obtain the relevant visa or Green Card . There are various visa categories, such as work, study, investment or family reunification. Each has specific requirements and a different application process, so it is advisable to consult the official information on the US Embassy website in Spain.
As well as the visa, you will need to prepare a series of documents to support your application. These may include birth certificates, criminal record certificates and academic qualifications, among others. It is important to make sure that all of these documents are duly legalised and, in many cases, translated into English by a sworn translator appointed by the Spanish Ministry of Foreign Affairs.
Legalising documents may require the Hague Apostille or specific procedures depending on the type of document and the country of origin. It is essential to find out about the legalisation and translation requirements to avoid delays or rejections in the immigration process.
Documents usually requested
Here is a list of the documents you are most likely to be asked for:
- Valid passport with at least 6 months’ validity remaining
- Form DS-160 (for non-immigrant visas)
- Form I-130/I-140/I-485 (for immigration/family/work)

It is essential to use specialist translation services that guarantee your documents will be accepted by the relevant authorities. On that note, companies such as Alos Soluciones Lingüísticas offer certified translations accepted by USCIS, with fast turnaround and ongoing support.
