I want to know if the immigration procedure is complicated?

The immigration process is relatively complicated and involves a wide variety of factors. However, Chinese immigrants are generally divided into three categories: work immigrants, family immigrants, and marriage immigrants. Among them, work-based immigration is the most complicated, and there are many aspects that need to be taken into consideration. It needs to be analyzed based on the applicant's own conditions, external factors and reality. Family immigration is divided into different types and waiting periods depending on the relationship between the applicant and the applicant. Marriage immigration is to marry a U.S. citizen and get a formal green card after two years. It is relatively simple.
