Argentina to the UK. Marriage then visa then return to UK

Hi, I might have the wrong end of the stick here!  I am the mother of a son who is about to marry a lovely girl in Argentina.  The hope is to then return to the UK to live together.  I am looking for any hints or help that can smooth the way.  Now retired I live in Norwich with my husband.
many thanks Rosiglow

Hey there Rosieglow

Welcome to Expat.com

There is nothing simple when it comes down to immigration and visas, and since the refugee crisis, it seems to have got stricter but not impossible.

Since July 2012, UK citizens and long-term residents applying to bring a non-EEA partner or spouse to live with them in the UK must meet a minimum income requirement of £18,600 per year before tax. For applicants who are also bringing dependent children the post-2012 threshold rises by £3,800 for one child and £2,400 for each additional child.

The income requirement must be met by the UK sponsor alone. Applicants cannot rely on offers of support from family members or other third parties. The non-EEA partner's earnings cannot be taken into account if they are working abroad or if they have a job offer in the UK but do not already have work authorisation. Those partners who are already working legally in the UK can count their income towards the threshold. This includes people on skilled work visas, whose holders must currently earn at least £20,800. A majority of people granted partner visas apply from outside the UK, however. In 2014, for example, the Home Office granted just over 26,900 out-of-country partner visas, compared to just over 8,900 in-country visas to people who were not previously recorded as holding a family visa.

Applicants who have cash savings can make up for a shortfall in earnings if the cash savings are at least £16,000 plus 2.5 times the shortfall. So, for example, someone with an income of £17,600 would require £18,500 in savings (=£16,000 + £2,500). People without income can qualify if they have cash savings of at least £62,500.

UK sponsors who are receiving certain disability-related benefits are exempt from the £18,600 threshold. The threshold also does not apply to EEA citizens, whose free movement rights under European law allow them to bring non-EEA spouses with them.

There is a way to avoid this though.
