Immigrants should be expected to learn English before coming to Britain - or be enrolled on compulsory language classes when they arrive, according to a parliamentary report.
MPs and peers also called on ministers to consider a radical overhaul which could see regions handed immigration powers in place of the current "one size fits all" system.
The report from the All Party Parliamentary Group (APPG) on social integration follows a landmark review which last month warned the country is becoming more divided as it becomes more diverse.
That inquiry from Dame Louise Casey called for more English classes for isolated groups and suggested ministers should consider whether immigrants intending to settle in Britain should swear an "integration oath" on arrival.
In its report the APPG said that integration should begin upon arrival in the UK and described speaking English as "the key to full participation in our society and economy" and a "prerequisite for meaningful engagement with most British people".
The study said: "The APPG believes that all immigrants should be expected to have either learned English before coming to the UK or be enrolled in compulsory Esol (English for Speakers of Other Languages) classes upon arrival."
The Government was urged to reassess the current "one size fits all" approach to immigration policy and consider reforming the system to more actively shape immigrant settlement patterns within the UK.
It suggested that a devolved or regionally-led system could draw on the model used in Canada, where provincial governments can set region-specific requirements for immigrants.
The paper raised the prospect of region-specific visas with quotas for their dissemination agreed by devolved administrations or city regions.
Net migration to the UK has been running at or close to record levels of around a third of a million - well above the Government's target of below 100,000.
Labour MP Chuka Umunna, chair of the APPG, said a "meaningful" integration programme was needed.
Jon Yates, of social integration charity The Challenge, called on the Government to consider the recommendations in the report, adding: "It is no longer enough to focus solely on the numbers of immigrants arriving in the UK, while ignoring what happens to them and their host communities after arrival."
