From then on, the k-3 visa was created. So the spouses of foreign can stay in the U.S. while they are waiting for the approval of the I-130 petition. When the I-130 is being processed, the spouses don't have to remain abroad.
Who can get the k-3 visa?
As follow you can get the answer who can:
if you must a U.S citizen and marry a foreign;
the United citizen spouse has a relative petition filed for the person;
try to enter the U.S and wait the approval of the petition and subsequent lawful permanent resident status. And,
If the Form I-129,petition for Alien fiancee, has been approved, the Alien spouse has to forwarded to the American consulate in his/her own country to apply for the K-3/K-4 visa. If the marriage took place in the alien spouse's country and there is a consulate of United States which issues immigrant visas in this country, the spouse has to apply for the k3 visa in his/her own country. The alien spouse can apply for her/his k-3 visa at jurisdiction over the current residence, if the marriage took place in the United States.
If the alien spouse who gets a k3 visa has a child who is under 21 years old and has not gotten married, the spouse's child can get a k-4 visa.
Work Permit
Once in the U.S. in K-3 or K-4 status, you are eligible to apply for a work permit while the cases are pending. Keep in mind that you do not need to apply for a work permit once you adjust to permanent resident status. You should receive a permanent resident card if you are the permanent resident. The card will prove that you have a right to live in the U.S permanently.
Go abroad and leave the United States
When you are applying for a k-3/k-4 adjustment status, at the same time, you can travel outside the United States and return using your unexpired k3 or k4 nonimmigrant visa.
When done correctly, the K-3/K-4 visa category can significantly reduce the time that spouses are separated while waiting for immigration status. The K-3/K-4 visa category is a relatively new visa category; therefore, you may wish to consult with an Immigration Attorney with experience with the K-3/K-4 visa for assistance with your case.
