Work Permit Documents for Foreign Workers: A 12-Item Checklist
A foreign worker who arrives with missing papers is not a hire. Most delays in international recruitment trace back to the file: an expired passport, a police certificate from the wrong authority, a diploma without the attestation the route needs, or a contract that does not match the job the permit was filed for. For Heads of HR and founders at companies of 50 to 1,000 people, knowing what a complete file contains is the fastest way to spot weak partners and avoid stalled applications. This checklist sets out the twelve work permit documents a foreign worker file usually holds. The exact list is route-dependent: it changes with the destination country, the permit type, the occupation and the worker's country of origin, and the competent authority always decides what it accepts.
International Strategic Hiring Choices

Why the File Decides the Hire
A work permit or single permit application is only as strong as the documents behind it. Authorities assess what is in front of them. If an item is missing, out of date or not in the required form, the usual result is a request for more information, a pause or a refusal, and the worker stays where they are while the site waits.
That is why a serious recruitment partner treats the file as a standard, not a formality. Screening comes first, so unqualified candidates never reach the document stage. The document pack is then assembled and checked against the route before anything is filed. The employer should receive the checklist for its route before filing, not a promise that "paperwork is handled".
Identity and Eligibility Documents
These items prove who the worker is and that nothing in their history or health blocks the route. They are the most common source of avoidable delay, because several of them expire or must be issued recently.
1. A valid passport
The passport is the anchor of the whole file. Check that names and dates match every other document exactly, that there are blank pages for visas, and that remaining validity covers the permit period the route requires. Many routes expect validity well beyond the planned stay, so a passport close to expiry should be renewed before filing, not after.
2. Photographs and civil documents
Most applications need recent photographs to a defined specification. Some routes also ask for civil documents such as a birth certificate or, where family members are involved, marriage records. Ask early which ones apply, because obtaining and legalising civil records can take time in the country of origin.
3. Police clearance certificate
A police clearance or criminal record certificate shows the worker has no disqualifying record. Routes differ on which authority must issue it, which countries it must cover if the worker has lived abroad, and how recent it must be. A certificate that was valid when collected can be too old by the time the file is filed, so time it carefully.
4. Medical certificate
Many routes and employers require a medical examination, sometimes at an approved clinic and sometimes with specific tests. Separately, the site may have its own fitness requirements for the occupation, such as work at height or food handling. Tell your partner which medical bars apply so the worker is examined once, against the right standard.
Skills and Qualification Evidence
Authorities and employers both want evidence that the worker can do the job the permit names. This part of the file links the person to the occupation.
5. CV and experience letters
A clear CV plus letters from previous employers confirming role, duties and dates. Experience letters should be on letterhead with contact details, because authorities and employers may verify them. Vague or unverifiable letters weaken an otherwise good file.
6. Education, trade certificates and skill test results
Diplomas, trade certificates, licences and the results of any practical or language test run during screening. For skilled trades such as welding or electrical work, the site may also need recognised certification. Some routes require formal recognition of foreign qualifications, so check whether that step applies to your occupation.
7. Attestation, legalisation and translations
Documents issued abroad often need to be attested, legalised or apostilled before the destination authority will accept them, and translated by a certified or sworn translator. Which documents need this, and in what form, is route-dependent. It is one of the steps most often underestimated, so build it into the plan from the start.
Employer and Job Documents
A foreign worker file is not only about the worker. The receiving employer, or a licensed partner where the law requires one, supplies documents that define the job and show the employer is entitled to hire.
8. Signed employment contract or job offer
The contract should match the permit application on job title, duties, pay, hours, place of work and duration. It should be in a language the worker understands, with a translation where needed. Mismatches between the contract and the filed application are a frequent reason files are questioned.
9. Employer registration and supporting evidence
Depending on the route, the employer may need to provide company registration details, tax and social security standing, and evidence connected to the vacancy, such as proof that the role was advertised locally or a labour market assessment. Some routes place these duties on the employer directly; others work through a licensed local partner. Confirm early who signs locally.
10. Accommodation and workplace details
Some routes ask for proof of accommodation or an address in the destination country, and details of the site where the worker will be employed. Even where it is not required for filing, having accommodation arranged and documented makes arrival and registration far smoother.
Filing, Visa and Arrival Records
The last part of the file records what was submitted, what the authority decided and what happens when the worker lands.
11. Application forms and filing record
The completed application forms, proof of fees paid, the submission receipt and every piece of correspondence with the authority. Keep a dated status log. Processing time is set by the authority, so the useful thing an employer can ask for is a regular status cadence, not a guaranteed day-count.
12. Visa, insurance and post-arrival registration
Once a permit is granted, the worker may still need an entry visa, travel or health insurance and, after arrival, registration of address or residence with local authorities. These documents complete the file and become part of the employment record that HR keeps after the worker starts.
Why the Checklist Changes by Route
There is no universal work permit documents list. Serbia's work-permit file is not Malta's single permit file, and both differ from routes elsewhere in the EU and beyond. Origin country matters too: police clearance, attestation and medical rules depend on where the documents are issued as well as where they will be used.
Treat any generic poster with caution. The right checklist is written for the route, the occupation and the site, and confirmed against the competent authority's current requirements. Our employer guides on the Serbia work permit and the Malta single permit show how much the detail differs between two corridors.
Common Gaps That Stall a Foreign Worker File
In practice, the same few problems cause most delays: names spelled differently across documents, a police certificate or medical that has gone out of date, qualifications without the required attestation or translation, a contract that does not match the application, and missing employer-side evidence. Each is preventable with a checklist and a pre-filing review.
A good rule: an incomplete pack stays in the country of origin until it is ready. Filing early with gaps rarely saves time. It usually adds a round of questions and leaves the worker and the employer waiting.
How ISHC Builds a Complete File
International Strategic Hiring Choices (ISHC) runs full-cycle hiring, from pilots and C-level leaders to frontline crews, plus HR staffing and overseas workforce placement. On overseas placements, the file follows our seven-step process: lock the occupation, site and route; source and screen; assemble documents; submit to the competent authority with a status cadence you can inspect; arrival; attached HR; aftercare.
You receive the route checklist before filing, and the employment file stays attached to the worker after arrival. ISHC prepares the file; the authority decides the permit. We will not open a file where no lawful route exists. Our track record includes 310+ workers deployed across Serbia, Croatia and Romania with licensed partners. That is the volume we stand behind, not a promise that any single file will be granted.
If you are planning foreign hires and want to know exactly what your file will need, send us the occupation, headcount, destination and start window, and our desk will map the route and its document list.
Questions Employers Ask
What documents are needed for a work permit for a foreign worker?
Usually a valid passport, photographs, police clearance, a medical certificate, qualification and experience evidence, attested and translated documents, a signed employment contract and employer-side documents. The exact list depends on the destination country, permit type, occupation and origin country.
Who is responsible for the work permit documents, the employer or the worker?
Both contribute. The worker provides identity, police, medical and qualification documents. The employer, or a licensed local partner where the law requires one, provides the contract, company documents and any labour market evidence. A recruitment partner can assemble and check the full pack.
Does a complete file guarantee the permit will be approved?
No. A complete file means the application is ready for the competent authority to assess. The authority decides whether to grant the permit and how long processing takes.
Do foreign documents need attestation or an apostille?
Often, yes. Many routes require documents issued abroad to be attested, legalised or apostilled and translated by a certified translator. Which documents need this, and in what form, depends on the route and the issuing country.
Is the document list the same for Serbia and Malta?
No. Each country sets its own requirements, and they change over time. Use a route-specific checklist confirmed against the current requirements of the competent authority.
