Nunc Pro tunc and material support bar

[Waiting-1]

I have a complex situation here and I hope someone may be able to help if he/she has been through the same experience. currently I'm a derivative asylee and my spuse is the principal asylee. We both applied for green card back in 2006. my wife got her green card after only few month and mine lingered on util I found out that they put my application on hold due to materials support bar (212)a 3 b. The bar was basically due to my wife's association with some political parties back home, but I was the one I gort slapped with that. Anyway due to some circumstances I will no longer be qualified as a derivative asylee and I want to apply for nunc pro tunc asylum. I'm worried that if I apply they will still hold my application due to the bar and a result I will lose all the benifits that I have now. My question is does this bar apply to nunc pro tunc applications as well? And do they still consider my ex-spouse political association as a bar tomy nunc pro tunc application? please help. thank you
