<human>:  What is the process for legal immigration to the United States?
<bot>: The process for legal immigration to the United States varies depending on the individual's circumstance. Generally, immigrants must establish their eligibility to migrate to the United States and obtain permission to enter the country. This is often accomplished through a visa application, although some other eligibility criteria can apply. Once the immigrant is approved, they will be issued a visa, which will allow them to travel to the United States and begin the process of becoming a permanent resident. This usually involves filing paperwork and attending an interview at a US embassy or consulate in the immigrant's home country. After the interview, the US Citizenship and Immigration Services will determine whether or not the immigrant is eligible to become a permanent resident. If approved, the individual will be issued a green card, which will allow them to live and work in the US legally.
