Yes, you can ask in TAW.
But the short answer is that it is up to the bishop which baptisms are valid, but generally speaking Orthodoxy will accept a baptism in a Trinitarian formula (baptized in the name of the Father, and the Son, and the Holy Spirit) with a right understanding of the Trinity (Christ as the Divine Son of God, and not a promoted angel or human, for example).
As such they generally accept most Christian baptisms. And since the Creed states "we believe in one baptism for the remission of sins" a person is generally not re-baptized.
However, no other group performs our Chrismation, which is part of the process for us, so everyone received into the Church is generally Chrismated. It is considered that if anything was lacking in the previous baptism, God knows and will complete it.
And I might also mention that the Russians were a bit cut off for a while and tend to strictness, so there have been cases of Russians re-baptizing. But that is coming more on line with the rest of the Church.
It's always an "ask the Bishop" question though.
ETA if this question means "do Orthodox consider Catholics to be saved?" the answer is that we don't judge the salvation of anyone - especially those outside our Church are not our place to say. Christ alone judges every person.
