What's the best way to apply for a visa sponsorship?

An H-1B visa is the most common way for employers to sponsor professional workers in the U.S. In order to qualify for this sponsorship, the employee must hold a position that requires at least a bachelor’s degree or equivalent experience in that field. Once obtained, an H-1B visa allows its bearer to stay and work in the U.S. legally for up to three years. After those three years, the visa can be renewed for up to six total years.

From an employer perspective, H-1B eligibility is much more complex. The employer must file the petition for the visa on behalf of the employee, who is not allowed to self-petition. Every company, regardless of size or age, must petition for one of the 65,000 H-1B visas that are made available every April 1st by U.S. Citizenship and Immigration Services. Note that 6,800 of those visas are set aside, per trade agreements, for immigrants from Singapore and Chile. An additional 20,000 H-1B visas are made available for workers with advanced degrees, meaning a master’s degree or above. Usually, more applications are filed than visas are available within the first week of April, meaning that the fate of the employee’s visa rests in the hands of an annual lottery.
