Tim Nikolaev

Senior Immigration Caseworker

Tim is a highly experienced immigration consultant who takes the lead in helping individuals and businesses with immigration issues. He holds level 3 OISC registration which allows him to undertake the most complex cases not falling squarely under the immigration rules.

Tim manages immigration casework at Kadmos and runs the sponsor management system for a number of business enterprises sponsoring migrant workers. He has a formidable track record of success in complex family immigration applications, applications for EU residence documents and applications for settlement, including applications made outside the immigration rules.

Tim regularly advises businesses on sponsor licence issues and runs mock audits and immigration compliance trainings for employers.

Tim is a bilingual English and Russian speaker. He holds a BA in economics and his commitment to supporting businesses with immigration concerns stems from his interest in history, politics and social sciences.

His patience and incredible attention to detail make him a real treasure, for clients and colleagues alike.
