My wife had another kid, what now?

Sorry, accidentally deleted the sentence that referred to him adopting if re-establishing himself as a father with full parental rights, which step-parents do not have (although this may be dependent on the state). If worse came to worst and he and his wife were to divorce, there could be issues with his visitation rights to the non-biological child if the only relationship they have legally is through marriage. He obviously wishes to raise the baby as his own, so adoption would be a consideration of interest if so.

Nothing to do with immigration.
