Texas:
Your diocese may be different, I’m not sure.
But the original poster’s question reveals that his wife is already Catholic.
tnjmcl2;6376012:
I was previously married and am going through the annulment process. I have been remarried for 14 years and my wife was just told that she can not participate in the Sacraments until my annulment is finalized - is this accurate information?
She’s not going through RCIA, but will, after (and only IF an annulment is granted) go through some sort of marriage prep with her civil husband.
I know that most people think of annulments as “automatic,” but that’s not how the Church views them. If the original poster receives a declaration of nullity, then he is free to marry his current [civil] wife validly. But if not, she will not be able to return to the sacramental life of the Church, because she is not married to him.
Typically annulments take around a year once the case is accepted. It’s worth the wait.
God bless,
