There is an interview for those who want to switch their driver's license that they obtained in their home country over to the Japanese driver's license.
ご質問ありがとうございます。
"There is an interview for those who want to switch their driver's license"＝「運転免許証を切り替えたい人には面接があります」
"that they obtained in their home country over to the Japanese driver's license."＝「母国で取得した運転免許証から日本の運転免許証にしたいときに。」
ご参考になると幸いです。
