Applying I485 to Fiance in F1 status

[sett]

Hi Gurus ;
I am going to apply the I485 in a week as I got the priority date to current .My question is when can I add my fiance as a dependent to I 485 , I know that Marriage registration is necessary , Is it OK if I apply the dependent 1485 to her before the fingure prints , or I have to apply before the priority date goes back ?

can anyone know what is the best way ?

-------------You don't add your fiancé, you need to file her I-485 as derivative. and you can do so as long as the dates are current.

I know that Marriage registration is necessary, Is it OK if I apply the dependent 1485 to her before the fingure prints, or I have to apply before the priority date goes back?

------------- Yes, you have to apply before priority dates retrogress and before your I-485 is approved.

can anyone know what is the best way ?

------------- apply your I-485/EAD/AP , get married and then apply your wife's I-485/EAD/AP (hoping PDs will remain current) ?
