After the children's exams, we have a temporary intention to travel abroad, but we have never been abroad before. I don't know what to prepare.

Different tour groups have different visa services. Generally speaking, tour groups will apply for group visas for applicants.

But for now, no matter whether the travel agency applies for a visa or not, you can't travel, because tourist visas in various countries have not yet been opened. Only Thailand can now apply for a visa to enter the country without isolation, and no other country has such a policy.

Especially if you have no experience of going abroad before, whether you have applied for a passport or not, it is more difficult to apply for a passport alone now, and it is even more difficult to go abroad to play.
