It looks like Korea’s “Bali-Bali” culture led to the Hyundai and LG workers not wanting to wait and go through the H1B visa process:
Many of those reportedly entered the US using B1 visas — issued for business purposes, such as attending meetings or signing contracts — or through the Electronic System for Travel Authorization visa waiver program for short-term stays. US immigration officials said that was the central issue in the raid.
Foreign nationals must acquire an appropriate visa such as the H-1B, L1 or E2 to legally obtain employment at workplaces located in the US. But as those visas can take months to obtain and their numbers are capped, they are often deemed impractical for companies that need to dispatch workers frequently or on short notice. Industry officials also complain that wait times for all types of visas have lengthened since the start of the Trump administration.
According to Korean media reports, the US allocates annual H-1B visa quotas to certain countries with which it has free trade agreements, including Canada, Mexico, Singapore, Chile and Australia. Despite having a free trade agreement with the US, South Korea does not receive a quota.
In response to the concern, an official from Seoul’s Foreign Ministry, who requested anonymity, noted that H-1B visas are distributed through a lottery. The official said that the ministry has repeatedly urged the US government and Congress since 2012 to create a separate visa quota for Korean professionals, such as via the proposed Partner With Korea Act.
