Amanda Sadlier

(she/her)

Lawyer (USA)

Amanda’s educational, professional, and personal backgrounds equip her to provide exceptional care and advocacy for her clients, whether seeking US immigration status or wanting to end their ties with the USA.

She first started working in an immigration law office over 25 years ago as a student near Cleveland, Ohio. The experience inspired her to study Spanish and International Studies at university and while living for a semester each in Spain and Ecuador. After completing her undergraduate degree, Amanda moved to the west coast, where she met her partner, a Kiwi from Wellington. In Seattle, she studied graduate level law and launched her immigration law career representing undocumented individuals seeking asylum and/or facing deportation.

After relocating to Auckland with her partner and their three children, she founded Optimum Law to offer US immigration law expertise to individuals and couples on the motu.

Amanda delivers legal services based in sound legal reasoning with consideration for the human experience and practical realities. She considers it a privilege to use her deep understanding of both the USA and Aotearoa New Zealand to guide Kiwis through the US immigration system.

Outside of legal work and family life, Amanda is an avid reader (and proud supporter of the Auckland Writers Festival), outdoor enthusiast, and amateur baker.
