Did you suffer degrading treatment from BLS counter staff?Were you forced to pay for a service you didn't want under the threat of not receiving your documents?Have your passport been held for months without a response?Filing a complaint on the BLS web mailbox is usually futile.We show you the official channels of the Spanish State where your complaint has legal and audit consequences.
The Legal Framework of Claims in the Spanish Administration
BLS International is not an autonomous entity with legal impunity: it is an external contractor of the General State Administration (AGE) that provides a subcontracted public service.Royal Decree 951/2005 guarantees the right of all users of public services to make complaints and suggestions about the operation of consular offices and their collaborating companies.
Complaints submitted through the official channels of the Ministry of Foreign Affairs (MAEC) do not remain in the BLS trash can: they enter the general registry of the State and count negatively in the evaluation documents and contractual penalties that the Spanish Government applies to the company.
Channel 1: The Official Book of In-Person Complaints at the Visa Center
By law, every BLS visa center must have official sheets from the Book of Complaints and Suggestions of the General State Administration.Do not accept a 'blank sheet of internal BLS suggestions': require the official format in triplicate on Spanish Government letterhead.
Fill in the facts with dates, exact times, names of the employees involved and the irregularity committed.A sealed copy remains in your possession, another in the center and the third must be sent to the Consulate General of Spain within a maximum period of 48 hours.

Key Practical Tips
What the team recommends before you file anything:
- Maintain a strictly factual and professional tone. Complaints containing insults or generalizations are filed outright, while complaints citing articles in the specifications or involuntary charges trigger consular inspections.
- Filing a formal complaint can never jeopardize the resolution of your visa. Complaints are processed by the MAEC services inspection, while your visa is resolved independently by the consular section.
Required Documentation Checklist
- Complete identification data of the claimant and visa file number.
- Date, time and exact BLS branch where the events occurred.
- Identification of the window staff or assigned counter number.
- Invoices, bank receipts or screenshots that prove the irregularity.
- Presentation through the MAEC Electronic Headquarters or triplicate Official Book.
