Hi there! That's wonderful! What did your son study in the Netherlands?
The job market in Spain is tough as the country suffers from high unemployment and low wages. Getting a visa sponsorship is difficult, however, some roles that are in demand may qualify for the highly qualifeid visa (tech, finance, senior management).
An easier route to Spain is through the digital nomad visa (DNV). If Chris can get a qualifying remote job that is based outside of Spain, he could apply for the DNV and take his remote job to Spain. In this case he would not require a visa sponsorship. This is the most popular route right now for remote workers who want to move to Spain.
After 2 years on the digital nomad visa in Spain, since he is a Colombian citizen, he could apply for Spanish citizenship. After applying for citizenship the waittime to a response/approval is generally 6 months to 2 years.
I hope this helps! Please le us know if you have any quesitons.
