Questions from employers
No. We work with employers of every size, from startups to large organizations. Size rarely changes which visas you can use. It can change some government filing fees, and a new company may need more proof that it can pay the wage. The type of employer can matter more: universities, their affiliated nonprofits, and nonprofit or government research organizations can file H-1B petitions outside the lottery.
Check the timing first. The H-1B has one lottery a year, and registration usually opens in March. The L-1, TN, and O-1 have no lottery and can be filed when you need them.
Often, yes. The worker can usually move to your company without another lottery. You file a new petition, and in many cases the worker can start once it is filed. Get advice before the worker resigns.
Usually more than a year, and often several. Most start with PERM, a Department of Labor process. Workers born in some countries, such as India and China, can then wait years more for a visa number.
Yes, but the visa has to fit both the business and the owner. Owners often use the E-2, L-1, O-1, or EB-2 national interest waiver.
Yes. Send us a list of your open cases and their deadlines, and we coordinate the file transfer with your current counsel.
