This will help you in deciding what temporary work visa to apply for if you qualify for more than one temporary work visa by understanding how they are similar.
1. Temporary Work Visas
L-1, H-1B, and O-1 visas are all temporary work visas, which means they do not last forever, expire after a time period, and do not lead to a Green Card.
2. Can Be Renewed
All three of these visas can be renewed. An L-1A visa is initially granted for up to 3 years (one year for new office) and extendable up to 7 years. An L-1B visa is initially granted for 3 years and extendable up to 5 years. An H-1B Visa is initially granted for 3 years and extendable up to 6 years. An O-1 Visa is initially granted for up to 3 years, can be renewed in one year increments as long as applicant maintains the employment, or the Applicant can do a whole new renewal application for 3 years.
3. Dual Intent
When applying for the visa, you do not need to demonstrate ties to your home country, and you can apply for a Green Card while still on the visa without losing your current visa status.
4. Premium Processing is Available
You can do premium processing for these visas, pay an extra fee, and get a decision in 15 days.
