What is the ruling on the marriage of a Muslim man to a Muslim woman who recently converted to Islam, without the approval of her non-Muslim parents, knowing that the young man's parents stipulate the approval of the girl's parents?

Your marriage to a Muslim woman whom you wish to help live an Islamic life is a commendable and rewarded act, and it falls under cooperation in righteousness and piety. Try to convince her family with kindness and gentleness. If that is not possible, the marriage contract can be concluded in a Sharia court in another country, while staying away from dangerous areas, and attempting to win over her family with gifts. Work to soften your parents' hearts to gain their approval. If the dangers are real and certain, we do not advise you to burden yourself with more affliction than you can bear. Rather, be patient and seek your reward from Allah, for "whoever fears Allah - He will make for him a way out."
