Unfortunately, I do not have another choice because I Am Stateless I don't have a country to go back to.Are you working with an immigration lawyer?
I don't believe there is any point in submitting another H&C application until you know the PRRA decision. If the PRRA decision is negative, a second H&C application won't stop removal. If PRRA does end up being negative, then you will either want to appeal to the Federal Court or request to defer removal. You'll want to be working with a good lawyer to do either of these.
and I don't think it's a good idea to appeal to the decision.
I think it's better to submit a new case with a new lawyer to gain the time.
now it's more than 4 months I am waiting for the refused letter to know the reason.
Please advice ..
