If I have a green card and I want to bring my fiancee to the USA as soon as possible what should I do?

There is no visa category by which a Lawful Permanent Resident (holder of a "Green Card") may sponsor a fiance for immigration benefits. A Permanent Resident may marry a fiance abroad and then apply for consular processing for the foreign national wife to come to the United States. Alternatively, depending upon the fiance's circumstances (such as job skills and qualifying job offer), she may be eligible to come to the U.S. with a different type of visa. It would be wise to consult with an immigration attorney who, after learning all of the relevant details, would be able to advise about immigration-related eligibilities, options and strategies. Some immigration law firms, including mine, offer legal services on a "flat fee" basis so that a client will know the total expense from the very beginning, and a few immigration law firms, including mine, offer an initial consultation free of charge.
