Father who applied for son\'s I-130 passed away

[father-son]

My father who was a naturalized US citizen passed away. He had filed an I-130 for me under the third category (married children of citizens), which was consequently approved and I was given a priority date.

I have three brothers here, who are naturalized US citizens but none of them have filed I-130 for me. My wife also has two citizen brothers here, one of whom has recently filed a petition for her, but the wait on siblings petition is at least 12 years.

Please advise me on how to proceed when a visa number becomes available, especially the interview. Is there is any chance of getting GC through my father\'s petetion prioroty date?

Thanks
