Border Agency staff processing visa applications from Africa are "acting
unfairly" and wrongly refusing entry to the UK, an independent report
claims.
Chief inspector to the UKBA, John Vine, said many visas were
incorrectly rejected after employees "disregarded or misinterpreted"
evidence. Some applicants were being refused for failing to provide information that had not been originally requested, he said.
The agency said it took the findings "seriously" and would improve training.
Mr Vine's inspection ran between May and July 2011, examining the applications handled at four UKBA posts in South Africa, Nigeria, Kenya and Croydon, south London - which deals with Algerian-based applications.
He reported claims by UK Embassy staff in Algeria that the visa delays had caused "reputational damage" to the UK.
And in a review of 135 visa applications from Nigeria, his report found the UKBA had made a "serious error" after 14 cases had accidentally received "indefinite leave to enter the UK" - rather than the usual 27-month limit.
In some cases, it found UKBA staff had failed to retain documents backing up their decisions.
The UKBA said there were several routes of entry to the UK which can lead to settlement. The length of time a migrant has to complete before being eligible to apply for settlement depends on which route they enter, they said.
Visas to the UK enable some successful applicants to stay and work in the country for two years, with an option to apply for permanent residency at the end of that period.
This relates only to spouses, civil partners, unmarried partners or same sex partners from outside the European Economic Area (EEA) of a British citizen or person who is settled in UK.
Various reasons for visa rejections were listed in the report. In one case, an applicant wishing to visit his uncle in the UK was turned down because they had different family names.
'Frustrating' UKBA's visa bases in Abuja, Nigeria; in Pretoria, South Africa; and Nairobi, Kenya had "performed well" to meet customer service targets, Mr Vine found.
But staff at Croydon's Visa Section in the UK had been "poor" in processing applications made in Algiers, Algeria.
Mr Vine said that little progress had been made by the UKBA in a number of areas, even though recommendations had been made in previous inspections.
"This is especially frustrating", he said, "considering the agency has accepted the recommendations, and yet I continue to identify the same issues.
"I would now like to see these recommendations being embraced by the agency without delay to ensure that there is a real improvement in the quality and consistency of decision making."
A UKBA spokesman said the agency was prioritising improvement.
He said: "We take the independent chief inspector's findings seriously and are making reforms, which include providing detailed guidance to applicants and improving the training for staff handling visa applications.
"The UKBA must offer a high quality service for genuine applicants while ensuring that those who do not meet the immigration rules are prevented from entering the UK," he added.
"We announced important changes to the family route on 11 June, including an increase to this probationary period.
"For those entering on or after 9 July this year the period will be five years. The migrant has permission to work in the UK during this period."
Those entering the UK under a work route need to complete a five-year period before being eligible to apply for settlement.
