You may get a visa, be sponsored by relatives for a green card or get a green card through your own eligibility in order to migrate to the United States..
Immigrant and non immigrant visas:
US visas would help you enter the U.S. Immigrant and non immigrant visas are two categories that would help in the person’s visit. Immigrant visas are issued to foreign nationals seeking permanent residence in the U.S. Such applicants can apply for an immigrant visa at a consular office of the Department of State. After the visa is issued, they can enter the U.S. and become legal immigrants once they pass through the port of entry. Non immigrant visas enables a stay for a limited period of time with a specific purpose.
There are around 20 types of non immigrant US visas for people traveling to the United States temporarily. The number of immigrant US visas are more for those coming to live permanently in the United States. The purpose of your US travel determines the type of visa you need.
The entire process of US visas needs careful attention. In spite of having all the documents and meeting all the requirements, individuals often get the visa application denied. A lot depends on the Visa Interview, whether you successfully get the visa or not. All applicants above the age of 14 should ensure that they sign their application form. If the applicant is below 14, either of the parent can sign the application form. Always enter your current address on the application form and not the permanent address.
Have the photographs taken per the specifications. Follow complete instructions and the procedures involved in getting the Visa. There should be no difference in any of the information given by you and by your visitor. Fill all the applications neatly and completely. Also be aware of what you have filled in the form. Often it happens (specifically in parents’ case) when children / sponsor fill out the application and the applicant him/her self are not aware of what information is provided. And always give correct and authentic information.
Also verify if details such as name, date of birth, etc match with the information on your passport.
In case you decide to leave your spouse and children behind in your country, be prepared to detail how they will support themselves in your absence. This can be a spot of bother if you are the primary source of income for your family. If the consular official gets the impression that your family will need you to remit money from the United States in order to support themselves, your visa application will be denied. If your family will join you in the US at a later time, it is helpful to have them apply at the same post where you applied for your US visas.
