This usually depends on the company's specific policies, but from the perspective of visas, if most countries go abroad for training, if the company does not write a letter of guarantee to bear all the expenses, the visa officer will not give you a visa, so you will basically bring some living expenses, mainly meals, and money to buy some gifts for your friends. The company will definitely give you a policy for such a large fee, so you'd better consult clearly before you go.
