Background Verification and Skill Audits in Cross-Border Hiring

This guide shows you how to check overseas candidates before you hire them in volume. You get a simple plan: what to check, how to confirm certificates, how to test skills, how to handle police records and data, and what to ask your agency.

Why paper alone is not enough

In technical jobs, one wrong hire can cause an accident or stop a project. A certificate can be fake, or belong to someone else. And a person with no certificate may be the best welder in the group.

The International Labour Organization (ILO) notes that access to skills recognition, especially for low- and medium-skilled migrant workers, is often limited¹. So you need two kinds of checks. Document checks tell you if the person and their papers are real. Skills checks tell you if they can do the work.

Step 1: Decide what each job really needs

Before you start, write a short checklist for each role. A driver, a nurse and a scaffolder need different checks.

• Identity: passport or national ID, checked against the person you interview.
• Education and trade papers: only the ones the job truly needs.
• Licences: for example a driving licence or a trade licence, if the work requires one.
• Work history: past employers, dates and job titles.
• Practical skills: a hands-on test of the main tasks.
• Police record: only where the job or the destination country requires it.

The ILO's fair recruitment guidelines say employers should not keep personal data that is not needed to judge whether a worker fits the job, or to arrange their deployment².

Step 2: Confirm certificates at the source

A photocopy, a scan or a laminated card is a claim, not proof. Confirm it with the body that issued it. People call this primary source verification. It simply means you ask the school, training centre or licensing body directly.

1. Get the worker's written consent to contact the issuer.
2. Find the issuer's contact details yourself, from an official website or a government list. Do not use the phone number or email printed on the certificate.
3. Send the name, date of birth, certificate number and dates. Ask the issuer to confirm or deny each detail in writing.
4. Keep the reply with the candidate's file.

For degrees and diplomas from another country, use the national recognition centres known as ENIC-NARIC. For example, Norway's Directorate for Higher Education and Skills says that, as an ENIC-NARIC office, it can give information about education systems, accredited institutions and contacts for authorities in network countries³. It also helps employers find out whether a position needs formal recognition, and which authority handles it³.

Watch for: a school you cannot find on any official list, dates that do not fit the person's age or work history, and a candidate who will not sign a consent form.

Step 3: Test the skill, not just the paper

A practical test is the best way to see what a person can do. Run it in person or by supervised live video. Use the real tools and tasks of the job.

A good test has:

• A written list of tasks, the same for every candidate.
• A pass mark agreed before the test starts.
• An assessor who does not earn a fee for each worker who passes.
• A recorded result, such as a score sheet.

Some destination countries run their own compulsory tests. Saudi Arabia's Ministry of Human Resources and Social Development says its Skill Verification Programme (SVP) was introduced to check professional qualifications before work visas are issued⁴. These schemes can change fast. In July 2026, Saudi Arabia stopped issuing work visas to Nepali workers in five job categories that need the SVP certificate, after Nepal sealed the testing institute and said it had no legal authority to run the tests⁴. The lesson: confirm that the test centre is approved by the authorities in both countries, and leave extra time in your hiring plan.

Also decide who pays. The ILO counts the cost of checking a worker's skills, qualifications and language as a recruitment cost². Its guidelines say workers should not pay recruitment fees or related costs². In the Nepal case, workers were asked to pay a 50 US dollar exam fee themselves⁴. Put the cost of tests in your own budget, and ask your agency to confirm in writing that workers do not pay it.

Step 4: Talk to past supervisors

A short call with a past direct supervisor shows how someone really works. Ask the candidate for the supervisor's name, then find the company's main phone number yourself and ask to be put through. This stops a friend from posing as the boss.

• What were the person's job title and dates of work?
• Which machines, tools or systems did they use every day?
• Did they follow safety rules without being reminded?
• Why did they leave? Would you hire them again?

Get the candidate's consent before you call. Write down the answers, the date and who you spoke to.

Step 5: Handle police records with care

Each country has its own process for police certificates. Confirm the exact steps with the issuing authority or the embassy before you ask workers to apply.

Some destinations make these checks part of the visa. In the UK, applicants for certain visa routes, such as Skilled Worker jobs in education, health or social care, must provide a criminal record certificate for every country where they lived for 12 months or more in the last 10 years, while aged 18 or over⁵. The same UK guidance says the law requires employers to do these checks in some cases in the health and education sectors, but elsewhere they are only best practice⁵.

Criminal record data is very sensitive. In the UK, the data protection regulator says it may only be processed under the control of official authority or where the law allows it⁶. It also warns that in most cases an industry blocklist based on criminal records will break the law⁶. The regulator says this guidance is under review, and other countries have their own rules, so check with a data protection adviser where you hire.

Ask for a police certificate only when the job needs it, and tell the worker why. A record need not mean an automatic no. Ask if the offence relates to the work.

Step 6: Protect the worker while you check

• Never keep passports. The ILO says workers' identity documents should not be confiscated or retained². Look at the original, take a copy and hand it back.
• Share data only with permission. The ILO says workers' personal data should not go to any third party without their prior written approval².
• Explain every check. Tell workers what you will check, why and who will see the result, in a language they understand.

What to ask your recruitment agency

1. Which checks do you do yourself, and which do you pass to another company?
2. How do you confirm certificates at the source?
3. Who runs your trade tests, and is the test centre approved by the authorities?
4. Who pays for tests, police certificates and document fees?
5. How do you store workers' data, who can see it, and when do you delete it?
6. What happens if a check fails after a worker has been selected?

Red flags

• Many candidates with the same certificate from the same unknown school.
• An agency that will not let you speak to candidates or watch a test.
• Workers who say they paid for their own test or certificate.

Frequently asked questions

How long do background checks take for overseas workers?

It depends on the country and the type of check. Some checks are quick, while others take much longer when an issuer or authority is slow to reply. Start them as soon as you shortlist candidates, and keep extra time in your plan.

Is a stamped translation proof that a certificate is real?

No. A stamp shows that someone translated the document. It does not prove that the original is genuine or that it belongs to the candidate. Always confirm the original with the body that issued it.

Should workers pay for their own skills test?

Under the ILO fair recruitment guidelines, the cost of checking skills and qualifications is a recruitment cost that workers should not pay. Build test costs into your own budget. Ask your agency to confirm in writing that workers are not charged.

What if a good candidate has no certificate?

Use a practical skills test. Many skilled workers learned on the job and never had the chance to get a formal paper. A fair, well-recorded test shows you more than a certificate does.
