My mum always applies for a multiple-visa entry successfully from Nigeria. She has never had any problems coming into the country and going back except for the last visit in 2014.
She missed her flight from Nigeria and had to come in on another flight the next day. However, this, I suspect, drew suspicion to her. She was stopped, interrogated and searched for a long time at Heathrow airport.
Some prescriptions that she was once given on previous trip by her GP from England were seen and queried. Also, I think she was challenged by having overstayed on segments of the multiple entries in the past as well.
She was eventually allowed in for about 3 months, and given a set time to leave the UK. She left in the given timeframe and has not had the confidence to apply for a visit visa since then. This is also coupled with the fact that she is getting on in age and I think she is dreading the complexities of the process of the visa application in her home country.
How do I apply for a visiting visa for her from here in the UK? I am the eldest of four children, and we all reside here. My father is long deceased and my mother is alone in Nigeria. She has a lot of ties in Nigeria and will not come to stay but to visit her children and grandchildren. I am in full-time employment and mum is financially stable. Do you think it should be a straightforward application process?
