Is it easy to go abroad with a party school degree?

no, the notary office of the party school is not allowed to do notarization. I have a friend who is a party school, but she saved the country, applied to the school, and then applied for a study visa in New Zealand. Fortunately, when you apply for a visa, you don't need to provide notarization of your diploma or authentication. That is, studying after going out is greatly restricted. But hers was also approved. I have gone to New Zealand.
