"Brexit negotiations are ongoing and there are positive signs but, for there to be an agreement, the prime minister will need to deliver on her December and March commitments of no hard Border, no physical infrastructure, and no related checks or controls", he told the Irish Independent. On the other hand, non-EU countries like India are subject to a strict visa regime and quotas under specific categories.
Khan expressed his views on Brexit and the called for a second referendum in an article that he wrote for Observer.
"The message from the British people was very simple".
The London Mayor explained that with negotiations in disarray and the very real prospect of a "no deal" Brexit - which would be disastrous for Britain, he now believed that the British people should also be given a say on whatever Brexit Theresa May's government managed to negotiate with the other European Union member states.

But many business chiefs and investors fear politics could scupper an agreement, thrusting the world's fifth largest economy into a "no-deal" Brexit that they say would weaken the West, spook financial markets and block the arteries of trade.
Part of the reason behind the Prime Minister's hopes that a Brexit deal could be reached, is that the European Union has said it wants to "de-dramatise" the Northern Ireland border issue, now one of the biggest sticking points in Brexit negotiations.
International Monetary Fund chief Christine Lagarde poured cold water on that notion Monday, saying "all the likely Brexit scenarios will have costs for the United Kingdom economy".

A "no-deal" would mean that Britain would exit the European Union without a transition period. May has told the BBC in an interview scheduled for broadcast Monday, Sept. 17, 2018, that she gets "irritated" by the debate over her leadership during Brexit negotiations.
The Prime Minister said that unless Conservative MPs accept the outcome of her negotiations with Brussels, "the alternative to that will be having no deal".
