Why Large Employers Create More Friction, Not Less
In the files I review, income is rarely the problem for employees at large tech companies. The friction shows up earlier, before the file ever reaches Spanish immigration authorities: getting the company itself to sign off.
Large employers tend to route international remote-work requests through more than one internal team, and each looks at the request through a different lens:
- Permanent establishment risk: corporate tax teams assess whether an employee working from Spain could create a taxable presence there for the company.
- Data protection and export control: security and compliance teams check whether accessing company systems or sensitive code from Spanish territory raises data-sovereignty or export-control questions.
- Work-location policy duration: many companies' work-from-abroad policies are built around short stints — a few months — and don't map cleanly onto a multi-year Spanish residence permit.
My role in these cases is usually less about the Spanish filing itself and more about drafting the employer paperwork so it satisfies what the UGE needs without triggering the internal objections above.
Getting Past Internal Legal, Mobility, and Tax Review
Permanent establishment and role scope: corporate tax counsel usually wants to know whether you hold authority to sign contracts on the company's behalf. The employer letter the UGE requests is issued purely for immigration purposes and doesn't grant any such authority — clarifying that your role is internal (engineering, product, operations) rather than external sales or contract-signing tends to resolve this concern quickly.
Social Security: HR teams generally don't want to register the company with Spain's Tesorería General de la Seguridad Social. Under the U.S.–Spain Totalization Agreement, an SSA Certificate of Coverage keeps you under U.S. Social Security instead, which is normally enough to close this concern without any Spanish registration on the employer's part.
Entity separation: under Ley 28/2022, you have to keep working for the foreign entity — you can't transfer your employment to the company's Spanish subsidiary under this authorization. If your employer wants to move you onto local payroll instead, that's a different visa (see below).
Documenting Equity Compensation for the Income Threshold
Compensation at large tech companies is often split between base salary and equity. For the 2026 threshold — €2,849 gross per month for a single applicant — base salary alone is usually enough on its own, and that's the cleanest way to build the file: contract, payslips, bank statements, employer letter, no need to bring equity into it at all.
If base salary alone doesn't clear the bar, vested equity that shows up on your payslips and W-2 can help — but unvested grants carry almost no weight, and the hierarchy of what counts matters. I've written the complete breakdown, including what to do when your base sits under the threshold, in my guide on whether RSUs and stock options count as income.
Vesting Equity and Cross-Border Tax
Once you're a Spanish tax resident — generally, once you spend more than 183 days in Spain in a calendar year — equity that vests after that point is typically subject to Spanish tax rules, regardless of when it was originally granted. Timing your move around a large upcoming vest without planning for this is one of the more expensive mistakes I see. The full mechanics, including how the Beckham Law interacts with vesting schedules, are in my guide on how RSUs and stock options are taxed in Spain.
Separately, moving to Spain doesn't automatically end your state tax residency in the U.S. — that's governed by your home state's rules on domicile and ties, not by Spanish immigration law. If you're relocating from California specifically, I cover the Franchise Tax Board angle in my California guide.
The Timeline Anchor: the SSA Certificate of Coverage
For W-2 employees, the SSA Certificate of Coverage is usually the document that sets the pace for the whole case. It confirms your employer keeps paying U.S. FICA taxes on your salary under the bilateral agreement, and it typically takes around three months to obtain. It's the first thing I start in every W-2 case, and a file is considerably stronger when it's accompanied by the certificate — or at least evidence that it's already been requested.
If Internal Approval Is Denied
Sometimes the internal review comes back negative — usually over permanent establishment or policy-duration concerns rather than anything about you personally. Two paths tend to come up:
- Transitioning to 1099 consulting: where it's commercially and legally workable, moving from W-2 employment to an independent contractor relationship removes the corporate payroll question entirely. See my guide on the Digital Nomad Visa for 1099 contractors.
- A transfer to a local entity: if your employer wants to move you onto the payroll of its Spanish subsidiary, that's a different immigration route — typically a Highly Qualified Professional permit or an intra-company transfer — not the Digital Nomad Visa.
In-Country UGE Application vs. Consular Route
Filing from inside Spain through the UGE while lawfully present on a Schengen stay yields a 3-year residence permit; filing through a Spanish consulate in the U.S. yields a 1-year visa. Most of my tech clients choose the in-country route for that reason — full comparison in my guide on applying from inside Spain vs. the consulate.
Statutory processing time at the UGE is about 20 business days. Positive administrative silence is the legal default, but in practice the UGE often issues a requerimiento when the employer letter is vague about remote authorization or compensation — precision in that letter avoids most delays.
Document Authentication Summary
| Document | Why the UGE Requests It | Required Legalization |
|---|---|---|
| FBI Background Check | Criminal record certificate required by law | U.S. Dept of Justice + Federal Apostille (U.S. Dept of State, DC) |
| University Degree | Required in most applications (unless proving 3 yrs experience) | Notarized True Copy + State Apostille |
| Employer Authorization Letter | Confirms remote permission, duties, and gross salary | Official letterhead + corporate signatory (no apostille needed) |
| SSA Certificate of Coverage | Demonstrates coverage under the bilateral agreement | Federal Apostille (U.S. Dept of State, DC) |
Only one document in the file needs notarization: your university degree, presented as an apostilled, notarized true copy. Employer letters, employment agreements, and paystubs don't need it. Full detail in my guide on FBI background checks and federal apostilles.
Frequently Asked Questions
Can I work for my employer's Spanish subsidiary on the Digital Nomad Visa?
No. Ley 28/2022 requires W-2 employees to work for an entity located outside Spain. Transferring onto a local Spanish subsidiary's payroll requires a different immigration route entirely.
Will my company's standard HR verification letter work?
Usually not without changes. Standard employment verification letters cover the basic facts but often miss the specific declarations the UGE expects — explicit authorization to work from Spain, for instance. See my guide on employer authorization letter templates for compliant wording.
What if internal approval takes months to come through?
Because the employer letter and the SSA Certificate of Coverage are both foundational documents, internal sign-off is usually the real timeline anchor — plan your filing date around it rather than the other way around.
For most employees at large tech companies, the employer-approval process is the longest part of the case, not the Spanish filing itself. Getting the employer paperwork right before it's signed avoids most of the delays that follow. My free assessment reviews your employment and equity documentation and flags issues before you file.
