Professor John Tulloch, who was injured in the London bombings, has criticised authorities who have said he must leave the country.
London Metropolitan University has set up a hot-line for students, following the news that it has had its visa licence revoked.
Immigration officers at Heathrow and Gatwick walk out over proposed changes to their pensions. The government say the strike's ineffective.
More than 100 people have complained to the Home Office after they were wrongly sent text messages accusing them of being illegal immigrants and telling them "to leave the UK", The Independent reported.
A Freedom of Information request submitted by anti-racism campaigner Suresh Grover - who also received the message - shows 39,100 individuals have been contacted in this way.
Of those, 103 have complained to the Home Office and 95 complained to Capita, the private contractor that issued the texts.
The Home Office said: "We have always been clear that this campaign was about encouraging illegal immigrants to leave the country voluntarily and was not targeted at particular racial or ethnic groups.
"In respect of the ASA's other findings, we can confirm that the poster will not be used again in its current format."
The Advertising Standards Authority said those who saw the poster would understand the claim "106 arrests last week in your area" to mean that during the previous week 106 people in the area - in which they saw the poster - had been arrested under suspicion of being in the UK illegally.

Because the data on which the claim was based related to a significant part of London north of the Thames rather than to the specific areas in which the poster was displayed.
[As] the data did not relate to the week prior to the campaign, we concluded the claim was misleading and had not been substantiated.
A Home Office campaign in London urging illegal immigrants to "go home" has been banned for using misleading arrest statistics. The campaign, which involved vans driving through six London boroughs in July and drew 224 complaints to the Advertising Standards Authority.
The Home Office has said it will reconsider future immigration campaigns after refugee organisations threatened legal action over its 'Go home or face arrest' adverts.
People who use the Refugee and Migrant Forum of East London (Ramfel), last month told the Home Office it had until August 8 to agree to ditch the "offensive" campaign or they would apply for a judicial review.
David Wood, the Home Office's director general for immigration enforcement has written to Deighton Pierce Glynn, stating:
[The] billboards stage of the operation has already ceased and the accompanying promotional material - leaflets, posters and adverts - does not refer to the number of arrests in the vicinity.
Instead, it sets out how an immigration offender can approach the Home Office without fear of arrest or detention. We do not consider it necessary to remove these latter campaign materials from public display and public premises.
Labour MP Chris Bryant said the Home Office advertisements to encourage illegal immigrants to leave the country were "poorly worded and tasteless, " and branded the government's immigration policy in general as adding up to "cheap and nasty gimmicks."
While poorly worded and tasteless ad vans were touring London begging illegal immigrants to hand themselves in we learned that the Home Office had not been fingerprinting migrants stopped at Calais for three years, and has not followed up 90% of its on intelligence on illegal immigration.
In short, the government's immigration policy adds up to cheap and nasty gimmicks, rather than serious proposals or practical measures to tackle illegal entry.
Human rights group Liberty said the Home Office has to "really think carefully" after the advertising watchdog launched a formal investigation into its "Go Home" illegal immigration campaign.
Liberty's Rachel Robinson told ITV News, "We know for a lot of people out there that's brought back terrible memories of the last 'Go Home' campaign we had in this country, which was of course orchestrated by the National Front in the 1970s.
"I think the Home Office have to really think carefully before they use this kind of language".
The Home Office said it is "in contact" with the Advertising Standards Authority after the watchdog launched a formal investigation into its "Go Home" illegal immigration van campaign.
A Home Office spokesperson said, “We can confirm that we are in contact with the Advertising Standards Authority over this investigation and will respond in due course.”
Labour's immigration spokesman Chris Bryant called the advertising watchdog's investigation into the Home Office's "Go Home" van campaign "another embarrassing blow".
Mr Bryant continued:
David Cameron and Theresa May can't even get the basics right, stumbling from one shambles to another.
You've got to question the Government's competence. We need effective action on immigration not offensive stunts.
A spokesman for the Advertising Standards Authority said that they had received 60 complaints about the Home Office posters.
Complainants have expressed concerns that the ad, in particular the phrase “Go Home”, is offensive and irresponsible because it is reminiscent of slogans used by racist groups to attack immigrants in the past and could incite or exacerbate racial hatred and tensions in multicultural communities.
Separately,some complainants have challenged whether the claim “106 ARRESTS LAST WEEK IN YOUR AREA” is misleading. They’ve also challenged whether it is misleading because it implies arrest is the automatic consequence of remaining in the UK without permission.
