Silvia Torres

"I've been receiving assistance from Débora Izquierdo for several months. We managed to start the Portuguese citizenship processes for me and my brother. She was always clear and willing to answer questions about deadlines, documentation and guidance throughout the process. We hope to finalize the entire process, which already has documents submitted and underway at the registry office, within this year. I recommend!"
Caio Proença

"When I lived in Portugal, I worked as a lawyer on Portuguese nationality cases, and I partnered with Débora, who proved to be a competent and attentive professional. Today, with responsibility, I recommend her work without a shadow of doubt."
