Is there a faster way to get my family here besides applying for a green card?

The Visa Bulletin issued by the U.S. Department of State shows that for foreign nationals of most nations, visas are currently available in the Family-Based Second Preference (FB2B) visa category - for unmarried sons and daughters age 21 years or older of Permanent Residents - for those with Priority Dates of September 8, 2008 or earlier, and visas are currently available in the Family-Based Fourth Preference (FB4) visa category - for siblings of adult U.S. citizens - for those with Priority Dates of August 1, 2002 or earlier. While that might look like delays of about 7 and 13 years respectively, in fact the waiting periods may be quite a bit longer, especially in the FB4 category for which a delay of 15 - 20 years or even longer may be realistic. Note: Republicans have been discussing eliminating the FB4 category entirely, and it is unclear what "grandfathering" or other options may be available to people with pending cases if new legislation were to be enacted. Aside from these considerations, it would be wise to consult with an immigration attorney who, after learning all of the relevant information about your relatives, would be able to advise about any other eligibilities, options and strategies. In pursuing the application process, representation by an immigration attorney can assure that the cases are properly prepared and fully documented, since failure to do that can cause very significant delays (or even more harsh consequences).

Through parents, it is usually faster. Consult with an attorney.
