How can I bring my future wife to US?

It may be possible for you to apply for your fiancé or under a K-1 visa. That usually requires that the couple have met at least once within the past two years. However, it is possible that U.S.C.I.S. could waive the requirement based upon your explanation. The application form is the I-129F and requires biographic data sheets from both of you along with passport type photos, evidence of your bona fide relationship and promise to marry within 90 days after her entry into the States. Dependent upon your present income, you may or may not have to obtain a financial cosponsor to have your fiancée enter the country. In addition, you should work to make your child support payments current as the avoidance of child support may ultimately bring you trouble with the law.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.

If you cannot travel, she will have to travel here.  She should apply for a tourist visa and come visit you here.  She could return and then you could file for a fiance visa for her to come back to the US and marry you.
