The K-1 Fiance visa filed with USCIS by your US Citizen boyfriend is normally processed through the applicable USCIS Service Center and varies in time of adjudication/approval/denial depending upon the current backlog in the number of cases being processed by the government. This period normally can run from 5 months to over a year. Once your US Citizen petitioning boyfriend receives an I-797 Approval Notice from USCIS you will need to set up a consular appointment with the US Consular post in your home country which was designated in his petition and follow the specific instructions given to you by the US Consular authorities for the actual issuance of the visa for your subsequent travel and entry to the United States [with the specific requirement that you marry the Petitioner within ninety (90) days of the visa issuance]. Once you are married and residing in the United States you should consult and engage an experienced immigration attorney to help you process your various concurrent spousal adjustment of status petitions for subsequent receipt of your "green card" (I-551).
