Here are some important points that you should remember about the H2B visa process:
A non-US citizen can’t apply for an H2B visa on his or her own. There should be a U employer that should sponsor them.
The employer should obtain a prevailing determination.
The employer should apply for the temporary labor certification and complete the recruitment process.
Once the recruitment is completed, the employer should file a petition for H2B temporary worker visa which should include the valid temporary nonagricultural labor certification and evidence that the foreign employee meets the minimum job requirements.
Application for the H2B visa should then be filed at the US consulate.
