You should never have to pay fees to a labor recruiter.
You must receive a written work contract in a language you understand.
It must contain detailed information about the wages, work duration, hours, benefits (including transportation, housing and meals or cooking facilities), and any deductions from your paycheck.
You have the right to be paid fairly even if you are paid at a piece rate.
Your employer must either provide or pay for inbound transportation and daily subsistence from the place from which you have come to work for the employer to the place of employment, or reimburse you for reasonable costs once you complete half of your work contract.
Once you complete the work contract, your employer must provide or pay for your return transportation and daily subsistence from the place of employment to the place from which you departed to work for the employer. Your employer may be required to reimburse your inbound travel and visa costs in the first workweek if your wages minus your expenses are less than the U.S. minimum wage. Your employer must also provide transportation from your employer-provided housing to the worksite at no charge.
You are exempt from U.S. Social Security and Medicare taxes on compensation paid for services performed in connection with your H-2A visa.
Generally, your employer must offer you employment for a total number of hours equal to at least 3/4 of the workdays in the contract period.
