"I applied for a work visa in Japan as an IT engineer. The document preparation was complex and I was anxious, but thanks to Mayuha Office's AI-powered preliminary review, they identified deficiencies early, making the application process smooth. My visa was approved in about 1.5 months, much faster than the usual 3 months - I was amazed by the speed. The polite support in English and assistance from Vietnamese staff were also reassuring. Highly recommended!"
