L-1 Intracompany Transfer Visa
The L-1 visa transfers managers, executives, and specialised-knowledge employees from a foreign office to a related US entity. Thai employees must show one continuous year of qualifying employment abroad and a parent, branch, subsidiary, or affiliate relationship between companies.
The US employer files Form I-129 with USCIS before the employee completes DS-160 at US Embassy Bangkok. L-1B specialised-knowledge cases require detailed proprietary expertise documentation. Thai Visa Centre helps organise Bangkok-side employment records.

The employee must have worked for the foreign company for one continuous year within the three years before transfer in a manager, executive, or specialised knowledge role. Employment records and job descriptions must match L-1A or L-1B criteria.
File Form I-129 with USCIS
The US employer files Form I-129 with the L supplement to USCIS. Include corporate relationship evidence, employment records, specialised knowledge documentation for L-1B cases, and US office business evidence.
Complete DS-160 after approval
After I-129 approval, the employee completes the nonimmigrant visa application online and schedules the consular interview at US Embassy Bangkok. Blanket L petition employers follow separate streamlined procedures.
Attend L-1 consular interview
Present passport, approval notice, employment evidence, and job description at Embassy Bangkok. The consular officer confirms the employee qualifies as L-1A manager or executive or L-1B specialised knowledge worker.

Additional guidance
L-1 for Thai employees
Thai nationals employed by a company with a qualifying US related entity may transfer in manager, executive, or specialised knowledge roles. The transfer must serve a legitimate business purpose for the US operation.
One-year employment rule
The employee must have worked for the foreign company for one continuous year within the three years before the transfer. Gaps, part-time work, or independent contractor roles may not count toward this requirement.
L-1A vs L-1B standards
L-1A covers managers and executives with up to seven years of L-1 status. L-1B covers employees with specialised knowledge proprietary to the company, a narrower standard requiring detailed documentation of unique expertise.
New office L-1 petitions
Companies establishing a new US office may petition for L-1 to send a manager or executive to set up operations. Initial approval is typically one year with extensions tied to business growth evidence.
Bangkok consular processing
After I-129 approval, the employee applies for the L-1 visa at US Embassy Bangkok with DS-160, employment documentation, and corporate relationship evidence from the petition file.
Bangkok coordination support
Thai Visa Centre helps organise Bangkok-side employment records and certified translations. Corporate structure analysis and I-129 petition strategy require US immigration counsel working with the US employer.
Common mistakes
These errors show up repeatedly in our Bangkok consultations for this visa category.
- Insufficient proof of qualifying corporate relationship
- L-1B petition without detailed specialised knowledge evidence
- Employment abroad less than one continuous year
- Job duties in US not matching L-1A or L-1B criteria
