The green card is granted for permanent residence in the US. Lengthy absences from the US go against this hence PR status is considered abandoned if the GC holder is outside the US for more than 1 year. In this circumstances you may not use your GC to re-enter the US. You need a re-entry permit or a SB (returning resident) visa. Some try to get round this by visiting the US before the year mark then repeating the pattern. The Inspector at a Port of Entry will ask length of absence from US - it is an offence to lie. In any case they have a record of your absence since your GC is swiped (or where I-551 stamp A#collected) at departure and the data sent to DHS. You can apply for a re-entry permit to prove your intent to retain permanent residence. IIRC the permits are issued for a max two years but you can apply for a second one. Having a home in the US and filing taxes also act as strong evidence of your intention not to abandon residence. Are either of you employed by a US company that has sent you to France?

No one knows what the laws will be in 4 years time. If they stay as they are then it should not be a problem for you to sponsor her GC as a USC spouse. There will be hefty fees, medicals etc that need to be considered. Likewise there is the issue of inadmissibility so she has to stay on the right side of the law at all times....some crimes of inadmissibility for US immigration purposes may seem petty compared to other jurisdictions. There is also the added issue of the state of your marriage in 4 years time (sounds negative but such happens). I recommend you file for a re-entry permit. She must file for this in the US so best look into flights if this is the plan.

She can use the VWP but must carry proof of compelling ties to France or other country that will make her depart the US after her 90 day max stay. This usually means a decent paying job, property/home, family in France. That you are in France and likewise have ties there can only help her case. Entry into the US at each occassion is at the discretion of the Inspector who has final say.
Bonne chance
