TriNet Group Inc. (NYSE: TNET), the fourth-largest US professional employer organization, acquired assets from Teleborder Inc., a provider of immigration HR services for employers.

The transaction closed in the first quarter and terms were not disclosed.

The acquisition bolsters TriNet’s capabilities for assisting small and midsize US businesses with the hiring, onboarding and retention of talent from other countries. The integration of Teleborder’s capabilities into TriNet’s platform streamlines work visa applications and enables companies to hire and manage international employees, according to TriNet.

Teleborder now operates as TriNet International Services. The full Teleborder team joined TriNet, with co-founder and former CEO James Richards now serving as director of product management at TriNet.

“In today’s global economy, mobility of employees is paramount for business success, said Jimmy Franzone, Trinet’s VP corporate development. “TriNet is committed to helping our clients focus on executing their business strategies by managing their HR. Teleborder’s unique expertise will serve as a building block for further development of TriNet products that help leading small and midsize businesses employ a global workforce.”

Teleborder was founded in 2013 by investors including Khosla Ventures, Y Combinator, Recruit Strategic Partners, IDG Capital, SV Frontier, East Ventures and 500 Startups.
