Every year, the US only offers 66,000 H2B visas to foreign workers, but recently, the number has slowly been increasing. Nevertheless, there is always a limit set. With this, if you want to make sure that you can make it to the allotted slots, you will need help from an expert H2B visa lawyer to guide you throughout the process.
H2B visa is typically just for one year. An extension of another year may be requested, but it is important to note that it isn’t always guaranteed. If you are lucky enough, you’d be able to extend to another year, and one more year if need be but petitions need to be filed every year.
