What is immigration compliance?

Immigration compliance is the set of legal obligations employers must fulfill when hiring, sponsoring, or managing foreign nationals across national borders. It covers the full employment lifecycle: verifying a worker's right to work before day one, maintaining a sponsor license, keeping records, reporting workforce changes to the immigration authority, and staying audit-ready.

The specific requirements vary by country, as does the authority that enforces them, but the exposure from non-compliance is consistent: civil penalties, damaged sponsor status, and in the most serious cases, criminal liability.

What immigration compliance requires of employers

Employers' immigration compliance obligations typically fall into four areas:

• Right-to-work verification: Confirming that every worker holds valid immigration permission for the role and country before employment starts.

• Sponsorship duties: Assigning authorization documents, monitoring employment conditions, and reporting changes to the immigration authority.

• Record-keeping: Maintaining copies of identity documents, immigration permissions, and verification results for each worker.

• Reporting: Notifying the governing authority when a worker changes role, leaves the company, or their immigration status changes.

Each country defines its own rules, administered by its own authority. USCIS administers compliance in the United States, the Home Office does so in the United Kingdom, and Germany's BAMF (Bundesamt für Migration und Flüchtlinge) sets the rules there. The practical obligations differ, but the underlying structure is similar.

Right-to-work checks and immigration compliance

A right-to-work check confirms that a candidate holds current permission that allows paid employment in the country before the hire begins. In the United Kingdom, the Home Office sets the obligation. From October 2026, it extends to organizations engaging individuals under a worker's contract or as individual subcontractors, under Section 48 of the Border Security, Asylum and Immigration Act 2025.

Where a worker's permission is time-limited (for example, a worker on a sponsored work visa), the employer carries an ongoing duty to re-verify before that permission expires. For employees under the UK's Core Protection regime, the employer must use the Employer Checking Service when a renewal application is pending, then repeat the check every six months until a decision is issued.

In the United States, USCIS requires employers to complete Form I-9 for every hire to confirm identity and employment authorization. Where a worker's Employment Authorization Document expires mid-employment, the employer must complete Form I-9 reverification using a different, valid document from the Lists of Acceptable Documents.

Sponsor duties and immigration compliance

Employers that sponsor foreign nationals carry the most demanding immigration compliance obligations. In the United Kingdom, a sponsor license from the Home Office is a prerequisite for hiring workers on routes such as the Skilled Worker visa.

UK sponsor obligations

License holders must maintain a record for each sponsored worker covering employment start date, job title, salary, and absences. The Home Office audits these records without advance notice, and gaps affect the sponsor's license rating.

From 2026, sponsors must also enable mandatory multi-factor authentication in their Sponsorship Management System (SMS) account by the Home Office's stated deadline. Failure to meet this requirement risks a downgraded license rating and affects the company's ability to sponsor future workers.

US sponsor obligations

In the United States, employers sponsoring H-1B, L-1, and O-1 visa holders file petitions through USCIS and assume legal responsibility for each worker's continued authorization. From November 9, 2026, USCIS requires sponsors to use the 09/09/26 edition of Form I-129 for nonimmigrant worker petitions. The agency rejects earlier editions.

Penalties for immigration compliance failures

Non-compliance carries consequences that vary by jurisdiction and severity. Civil penalties are the most common outcome, but loss of sponsor status and criminal liability are also possible.

Knowingly continuing to employ a worker without valid work authorization creates liability in the United States under the Immigration and Nationality Act (INA §274A, 8 U.S.C. §1324a). In the United Kingdom, failure to complete required right-to-work checks exposes the employer to civil penalties under the Immigration, Asylum and Nationality Act 2006.

A licensed sponsor that breaches its duties faces a reduced license rating or suspension. The Home Office and USCIS each publish current penalty schedules and revocation thresholds.

Immigration compliance for cross-border and remote workers

Cross-border and internationally mobile workers present distinct immigration compliance challenges. A worker employed by a company in one country but working remotely from another may still need a local work permit or equivalent authorization, depending on the destination country's rules. Some countries treat extended remote work as triggering local employment law obligations, even without a physical employer presence.

For companies managing international assignments, the compliance picture spans both the home country and the host country. Work authorization in the host country, payroll registrations, and benefits arrangements may all need updating. The governing authority in each country determines what qualifies as a reportable employment event, and requirements vary by jurisdiction.

FAQ

What does immigration compliance mean for an employer?

Immigration compliance means verifying that every worker holds valid authorization to work in the country and role, maintaining any required sponsor licenses, keeping records of verification and sponsorship, and reporting changes in a worker's status to the governing authority.

Who enforces immigration compliance?

Each country appoints its own authority. USCIS enforces compliance in the United States, the Home Office does so in the United Kingdom, and Germany's BAMF handles it there. Rules, audit procedures, and penalties differ across jurisdictions.

What are the consequences of immigration compliance failures?

Consequences range from civil fines to loss of sponsor status. Knowingly employing a worker without valid authorization can trigger criminal liability under the law of the relevant jurisdiction. The Home Office and USCIS each publish current penalty schedules.

Does immigration compliance apply to remote international workers?

In many jurisdictions, yes. A worker employed in one country but working remotely from another may need local work authorization, regardless of whether the employer has a physical presence there. The local immigration authority determines what is required, so rules vary by country.

How does an EOR help with immigration compliance?

An EOR acts as the legal employer in the host country, taking on the immigration compliance obligations on behalf of the hiring company, including work permit applications, right-to-work checks, and reporting duties. This is common when a company lacks a local entity in the worker's country.

Immigration and employment laws differ by jurisdiction, and the governing authority in each country and qualified immigration advisers are the definitive sources for current requirements.
