Abigail De Guzman has spent more than a decade working in Singapore's immigration services industry, helping foreign professionals and families prepare Singapore Permanent Residency and Citizenship applications. Over the years, she has developed structured case management systems, trained immigration professionals, and contributed to the preparation of thousands of applications.

She is known for taking a systematic approach to complex problems and believes there is a right way to prepare an application-one that begins with understanding the process before making decisions.

After years of seeing applicants struggle with conflicting advice and persistent misconceptions, Abigail began documenting the principles, frameworks, and practical methods used within professional case management. Those ideas became The Singapore PR Application Playbook.

Her work focuses on helping applicants understand the application process, organise information effectively, and prepare applications that are thoughtful, thorough, and well supported. She hopes this book gives readers the confidence to make informed decisions based on evidence, careful preparation, and a clearer understanding of how Singapore PR applications are built.
