What is the difference between a visa and a green card?

As someone who is interested in travelling to the United States, it's important to understand the difference between a visa and a green card. While both permit non-US citizens to enter the country, they serve different purposes and come with distinct privileges and restrictions. A visa is essentially a permission slip that allows you to enter the US for a specific period of time and for a specific purpose. For instance, if you're a tourist, you'll need a tourist visa, while if you're going to attend a conference, you'll need a business visa. Visas are temporary and expire once the specified time period is over. It's important to keep in mind that visas do not give you permission to live or work in the US. A green card, also known as a permanent resident card, is essentially a permit that enables non-US citizens to permanently live and work in the US. It's one of the most sought-after immigration statuses, as it provides many advantages such as the ability to access education, health care, and social security benefits. Green card holders are also allowed to travel outside the country, unlike those who have visas. If you're looking to move to the US permanently, obtaining a green card is the best way to go. But if you only need to visit the country for a short period of time, a visa may be the more appropriate option. Ultimately, the decision depends on your specific needs and goals. By understanding the differences between the two, you'll be able to make an informed decision.
