The K1 visa permits the K1 visa holder to enter the US for a 90-day period to marry the petitioner and apply for permanent residence (green card) and obtain an EAD. Once the visa is issued, the K1 visa holder has six months to enter the US for the purpose of marriage.
The K1 visa process is rather long and arduous. However, we will be happy to see you and your fiancé(e) through the process and make sure that things go as smoothly as possible. Mishandling of the K1 fiancé(e) visa application may result in lost time, visa denials or arrest and deportation of the fiancé(e) where the USCIS suspects fraud. If you are already married, then you may want to apply for a K3 visa.
Children of the K1 visa applicant may obtain a K2 visa to enter the US together.
