Naturalization Approval Case: Long-Term Work Visa Holder from South Korea Obtains Japanese Nationality

Case Overview | Naturalization from Long-Term Work Visa

In this case, the client was a South Korean national who had been living in Japan for many years on a work visa. While considering naturalization (acquiring Japanese nationality), they felt particularly anxious about the interview at the Legal Affairs Bureau and were looking for an office that could provide accompanied, end-to-end support including interview attendance. We supported them consistently from advance preparation (expected questions and key points) through attendance on the interview day and prompt handling of additional documents and corrections afterward, enabling them to proceed without hesitation and obtain approval for naturalization.

• Nationality: South Korea
• Status of Residence: Work visa (long-term residence in Japan)
• Reason for Consultation: Anxiety about the Legal Affairs Bureau interview and the wish to have a professional accompany them
• Our Support: Advance explanation of expected questions and important points / attendance at the Legal Affairs Bureau interview / prompt handling of additional documents and corrections
• Result: The entire procedure progressed without confusion, and the client obtained Japanese nationality (naturalization approval)

Customer’s Story | Interview Attendance Allowed Me to Proceed without Anxiety

This is the experience of a client who had lived in Japan for many years on a work visa and requested support for a naturalization application. Because naturalization requires not only document preparation but also prior consultation and interviews at the Legal Affairs Bureau, we clarified both “how to prepare for the interview” and “what will happen on the day” to create an environment where they could attend with confidence.

	Mr./Ms. K (South Korea)
	Requested Service: Naturalization application support (from work visa to acquisition of Japanese nationality)

I had been living in Japan for many years on a work visa and was thinking about naturalization, but I felt very anxious about the interview at the Legal Affairs Bureau, so I was looking for an office where a specialist could accompany me.

From the first consultation, ACROSEED was very thorough. They carefully explained expected questions and important points in advance, and a staff member attended the interview at the Legal Affairs Bureau with me, which allowed me to attend the interview with peace of mind.

They also responded quickly to additional documents and corrections after the interview, so there was never a moment when I felt lost during the whole procedure.

Having someone accompany me from start to finish was a huge advantage for me as someone who felt anxious about naturalization. I am very glad that I chose ACROSEED. Thank you very much.
