Can a single person apply for eb 1 immigration?

Of course. Single eb 1 immigration has nothing to do. The key is whether you meet the requirements of eb 1 immigration. Eb 1 immigrant visa, namely eb- 1 immigrant visa, allows multinational companies to send their senior managers outside the United States to their branches (or headquarters) in the United States to continue their senior management work. Eb- 1 Immigrant visas require companies in the United States to have recognized transnational relations with foreign companies outside the United States. Commercial entities in the United States are applicants, and senior managers sent from abroad are applicants. Before submitting the eb- 1 application, the US entity must be in full operation for more than one year. If it is within one year, senior managers sent from abroad can apply for L- 1 visa to enter the United States first.
