As long as TPS status is valid, she can file for GC. GC under EB2 takes almost 2 to 2.5 years if not delayed. That means, she has almost 21 months left if TPS is extended for another 18 months. Finger crossed but lets expect the TPS will extend for the next round as well. If it does not extend, govt will anyway provide some time before it gets terminated. So, better start ASAP to file GC based on TPS. If think Eb2 and Eb3 are both current. File I-140 PP to save time.
