Wait a minute
There is something wrong with this picture. Initially you said, she entered illegaly and now you are saying it was based on political asylum? First of all, no one enters as an asylee. You can enter as a refugee or ask for asylum at the port of entry but asylum status is never pre-approved and you cannot enter as an asylee.
Secondly, asylum status is not granted temporarily for a definite period. It is indefinite unless revoked by USCIS for a specific reason. So, you need to gather facts before asking questions so that we can respond in light of all the facts.
