About H 1B American visa

The lottery number of H 1B only means that you have legal status in the United States and can continue to stay in the United States on a work visa. If you don't go back to China and stay in the United States, you only need to get the H 1B approval notice, and your status is legal. If you go back to China, you must reapply for a visa at the American Embassy. You can't sign it in America now. It seemed possible a long time ago. Now, once you return to China, you must reapply for a visa at the American Embassy in China. How long the process is depends on whether you sign in in person or hand it in. If it is a natural delivery, it usually takes 2-3 weeks. If it is a face-to-face visa, you can make an appointment directly by phone, then take the materials to the embassy and immediately determine whether to pass or refuse the visa. If it passes, it will take 1 week for the passport to come back. H 1B is signed at one time, and the visa is valid for 3 months. You can only enter the United States once with this visa. H 1B status is valid for 3 years, which can be extended for 3 years, totaling 6 years, and there is no more time. This means that you have the identity of h1b. Whether you find an American company in China and enter the United States with an H 1B visa, or you find a work company in the United States to help you handle H 1B, you have this status. Generally speaking, from the date of 10 every year, if you want to leave the United States within six years, you need to re-sign a visa to enter the United States wherever you go, which is H1B. Generally, you need to sign in the country where your nationality is located, and you can enter the United States within three months, and you can only enter the United States 1 time. If you leave the United States again, you must get a visa again. At present, many people are afraid that it is not easy to get a visa when they return to China at school, but at least all my friends have never encountered this problem. They were all signed in the United States with F 1 Returning to China to visit relatives, their visas expired but their identity became invalid. They went to the embassy and signed an entry visa for F 1, and all returned to the United States smoothly. If you don't have a chance to return to China while you are at school and want to work later, you should find a company in the United States that can give you H 1B job status. Because of different majors, different graduate schools and different personal qualifications, the probability of finding a job in a company is different. As long as the company provides you with H 1B, your status in the United States will change, and H 1B will come down. Just an identity, not a visa. If you want to go back to China to visit relatives and then come back to work in the United States, you must apply for a one-time entry visa valid for three months and bring all kinds of materials into the United States. It doesn't mean that you changed your identity to H 1B in the United States, and you have an H 1B visa. This principle is the same as changing from other identities to student identities in the United States. Although the Immigration Bureau has recognized your student status, it does not prove that you have an F 1 visa. When you return to China and want to enter the United States as an international student, you still need to sign a new visa. Liujm0' s words seem to be what I said the last time I answered someone's question (except the last sentence). L visa is an expatriate employee of China company (need to work in the company 1 year or more). L visas can be used for multiple round trips, but it seems that the cost will be more.
