Mr. Javid plans to announce his pledge after releasing the UK government's white paper outlining Britain's future immigration systems.
The news comes after UK prime minister Theresa May's Cabinet struggles to resolve its stance on freedom of movement and fulfil its Brexit promises to "take back control" of Britain's borders after Brexit.
Speculation on introducing a £30,000 threshold on salaries of Tier 1 and 2 skilled migrants to the UK has fomented disputes between senior ministers, endangering the already delayed publication of the paper.
"It will be a single, skills-based immigration system built around the talent and expertise people can bring, rather than where they come from — maximising the benefits of immigration and demonstrating the UK is open for business."
Currently, EU nationals can work and live freely in the UK, but the new system will introduce visas for skilled workers and remove limits to high-skilled migration from doctors, engineers, and others.
Critics have hit back at the proposals, stating that focussing on earnings instead of place of origin will slow economic growth and cause migrant labour shortages.
"The Government has disgracefully labelled workers on less than £30,000 as low-skilled," Shadow home secretary Diane Abbot said. "Our economy and public services are kept ticking by this majority of workers."
Mrs. Abbot said that the government only claims to use a "skills-based" criteria for "meeting the needs" of the UK economy, but is really "using an income-based system which allows derivatives traders free movement but which excludes nurses, social care workers and other professions in which we have severe skills or labour shortages".
"The Tories are, once again, using crude anti-migrant rhetoric to try to cover up for their abject failure of managing the economy and the Brexit negotiations."
