Having found McMillan&Co. through Google reviews, I can now confidently say that they have the best lawyers I have ever dealt with. Sarah Caulton, in particular, made the process a pleasure —professional, supportive, and invaluable throughout my application. I highly recommend McMillan&Co. for anyone seeking immigration guidance.

I was introduced to Sarah Caulton at McMillan & Co. by a friend, and the experience has been delightful. Working through the INZ regulations can be daunting, but Sarah's expertise, and measured, precise advice helped us immensely. She was great in piecing together our strategy (based on our plans for NZ) as well as executing it.

I would recommend working with Sarah and McMillan to anyone looking to migrate to NZ.

Stars

Very satisfied with Sarah's services at McMillan. She was prompt, considerate and quite helpful and realistic with her advice. My immigration journey was greatly simplified because of her services. Highly recommend Sarah's services!

As recent immigrants from South Africa to New Zealand, we had the pleasure of working with the exceptional immigration lawyer Sarah Caulton and the friendly team at McMillan&Co. Their commitment to providing the highest level of service and support to their clients surpassed our expectations, and we are forever grateful for their hard work and dedication - especially considering the significant 11-hour time zone difference and ever-changing COVID complexities. Sarah's extensive knowledge and expertise in immigration law, along with her attention to detail and genuine interest in our family's well-being, made our experience with McMillan&Co truly exceptional. We highly recommend their expert immigration services to anyone seeking professional and compassionate guidance through the NZ immigration process.

Sarah at McMillan&Co. successfully helped me navigate my residency visa application process in 2021/22, which was particularly complicated and confusing due to visa changes and the Covid19 pandemic. Always very thorough, prompt and polite in our meetings and correspondence. 

Stars

The McMillan&Co immigration team led by Sarah has quite literally been one of the highlights of our past year. She and her team were professional, had extremely strong knowledge and managed our immigration process from start to finish which involved multiple complexities. We are so grateful we had a recommendation for this firm and cannot share that same positive recommendation enough to others. Thanks again for all your support and help.

Hiring the services of an immigration adviser with McMillan &Co was a great decision. Navigating through immigration NZ can be challenging.

Sarah, showed she had deep understanding of the process. She and all the staff I dealt with were remarkably professional and helpful. I could rely on them whenever I needed. Considering we were going through a difficult time with immigration during the pandemic, I am deeply grateful to her.

 

Stars

McMillan & Co were recommended to me by a friend.

My dealings have been with Sarah Caulton primarily. Sarah has always been prompt in assisting me, precise with her advice and efficient in her dealings with INZ on my behalf. She is obviously a subject matter expert in immigration law, but I would also endorse her pleasant demeanour.
Good advice doesn't come cheap, however; in the case of McMillan & Co, I'm satisfied with the quality of service and professionalism.
