Applying for B1/B2

Have a pending I-130 with priority date of 26 OCt 2002 In the F2B category, now my cousin wish for me to visit her in MARYLAND, My parents and siblings live in the states and I have been denied B2 Visa befor in 2002 , but I have also travelled to the US before as a child first in 1987 and 1992 with my father. QUESTION is I have 5 Years working experience in a bank, I have travelled to the UK,FRANCE,ITALY AND SPAIN regularly on holidays in the last 3 years. What are my chances of getting a visitors visa? If my chances are not bright, I might as well forget about applying for a visitors visa.
