What's the difference between H 1B and H2B visa?

H 1B is a work visa for professionals, which has a fixed quota every year and is often in short supply. In the past two years, all the places of H 1B were used up within the first week of release, so the Immigration Bureau had to decide the cases to be accepted by drawing lots by random machine.

H2B: H-2B, known as "non-agricultural short-term worker visa", is suitable for applicants who intend to come to the United States for temporary or seasonal work. Job categories include nanny, restaurant chef and enterprise, construction and gardening workers. , and the requirements for the applicant's academic qualifications and technical knowledge are relatively loose, and it is not necessary to implement the soft regulations of H- 1B requiring the applicant to be professional and work-oriented. The quota for H-2B is 66,000 in each fiscal year, and half of the quota will be distributed in the next two and a half fiscal years, that is, 33,000 H-2B places will be provided for application from March 10 to March 1 April/kloc-0 to September 30.
