Assistance to companies in cases involving the hiring of foreign workers

Companies with foreign workers at the airport
IN DIEM Abogados advises companies that host foreign employees, executives, professionals, technicians, speakers, business partners, or representatives in Spain, both in preparing the necessary documentation prior to travel and in providing urgent assistance should an issue arise at the border or airport.
For a company, an incident at an airport is not just an individual immigration issue. It can affect a key meeting, a technical assignment, a negotiation, an event, a business presentation, a corporate operation, or the execution of a project. Therefore, when a foreign national enters Spain for professional or business purposes, it is advisable to prepare the documentation in accordance with legal standards.
Assistance to companies regarding entry issues into Spain
In the business world, the main issue is often properly documenting the professional purpose of the trip. It is not always sufficient to simply state that the foreign national is attending a meeting or working on a project: it may be necessary to document who is inviting them, what activities they will be carrying out, for how long, which company they are associated with, and why their presence in Spain is consistent with the planned stay.
IN DIEM advises companies on how to mitigate risks before travel and how to act quickly if an employee, executive, technician, speaker, or foreign representative is already being detained or denied entry at the airport.
What the Company Should Review Before the Trip
Preparation should begin with a practical question: If border authorities request an explanation, can the foreign national clearly and with supporting documentation demonstrate why they are entering Spain?
Professional or business purpose of the post
The company must be able to explain the purpose of the trip: meetings, project implementation, technical assistance, internal training, participation in a conference, business negotiations, facility visits, audits, presentations, events, or specialized engagements.
This purpose must be consistent with the length of stay, the return ticket, the accommodations, the visa (if applicable), and the documentation carried by the foreign national. For more comprehensive travel planning, please consult the service to “Preparing for Entry into Spain”.
Invitations, agendas, contracts, and corporate documentation
Corporate documentation can be essential. Useful examples include business invitation letters, meeting agendas, contracts, purchase orders, corporate emails, event credentials, conference programs, project documentation, letters from the sending or receiving company, and proof of the professional relationship.
If you are also staying with a private host or combining a private visit with a professional activity, you may need to review the invitation letter to enter Spain—though this should not be confused with the business documentation justifying the business trip.
Visa, Proof of Financial Means, and Consistency in Documentation
When a foreign national travels with a visa, it is important to verify that the visa is consistent with the actual purpose of the trip, the dates, the length of stay, and the professional documentation. The Visa issues at the airport can arise even if a visa is present if the documentation as a whole raises doubts.
You can also check the financial means required to enter Spain, especially when the person must prove they have sufficient personal funds or when the company covers certain travel, lodging, or living expenses.
The consular information and the applicable requirements may vary depending on nationality, type of trip, visa, and specific circumstances.

When a problem has already occurred at the airport
If the foreign professional is already at the airport and cannot proceed with entry, the company must act quickly and in an orderly manner. This may involve a document check or a situation where a person detained at the airport, or being held in airport detention room , or a possible denial of entry at the airport.
In these cases, the company can play an important role by providing corporate documentation that substantiates the reason for the trip: a business invitation, a meeting schedule, a contract, event accreditation, an explanatory letter, contact information for the person in charge in Spain, project documentation, or proof of the professional relationship.
To provide additional information, IN DIEM has analyzed the common reasons for being denied entry at the airport; however, business assistance always requires an assessment of the specific case and the available documentation.
How IN DIEM Abogados Can Help
IN DIEM advises companies on both preventive measures and emergency response procedures in the event of an incident at an airport. Before the trip, we verify that the business purpose, corporate documentation, accommodations, financial resources, visa, return ticket, and expected duration of the stay are consistent with one another.
If the incident has already occurred, we advise the company on what documentation to gather, how to organize the information, and what legal actions may be considered based on the status of the proceedings and the specific circumstances.
If a formal decision has already been issued, it may be necessary to consider filing an appeal against the denial of entry, always taking into account the stated reasons, the deadlines, and the available documentation.
Legal intervention does not guarantee entry into Spain or an immediate resolution of the issue, but it does allow for a more organized, strategic, and technically sound approach.
Spanish immigration law is based, among other regulations, on the Organic Law 4/2000 and the current Immigration Regulations.
