US Immigration Visas

Finding a job in the US is a dream for millions of people worldwide. Besides that, there are hoards of tourists who visit the country every day. Everyone who enters the US requires a non-immigrant or an immigrant visa.

The United States Citizenship and Immigration Services (USCIS) is responsible for issuing these visas. All US immigration and non-immigration visas start with the Letter "I," followed by numbers. If you are applying for a US visa, you should know that none of the forms directly grant a US visa. However, once approved, you can use these forms to stay or extend your stay in the US. These US immigration forms also authorize you to work in the US.

Below is a list of the most important US immigration forms you may encounter before making your journey to the US. Let's unravel each form, its purpose, and the procedure to fill it correctly.
