how can I speed up the immigration process for family, my category is F4 brothers and sisters of U.S. citizens

I assume that with your reference to a 1997 visa bulletin date for the F-4 category, your family is born in Mexico. The rest of the world except for India, Mexico, and the Philippines is already up to the year 2003 for immigrant visa availability in the F-4 category. Unfortunately there is no speeding up of the category unless the dependent spouse is born in another country. In that event, there could be a cross-charge of the dependent’s country of birth instead of Mexico. I would suggest that if your father or mother has education or an employment based skill that could be the subject of employment sponsored immigration, that would probably be a better way to go. The EB-2 category for persons with advanced degrees (or bachelors +5 years of progressive experience) is up to February 2014 for Mexico born, and the EB-3 category for skilled workers or those who only have a bachelors degree is up to May 2016. (I note that the EB-2 category is expected to rebound to a more current date in the October visa bulletin).
