Scared me there
Meeb! I did a bit of net research:
United Kingdom Ancestry
Commonwealth citizens who can produce the necessary documentation proving they have a grandparent born in the United Kingdom may apply for entry clearance which would enable them to seek or take employment in the UK for up to four years without the need to apply for a work permit.
See information sheet INF.UKGP
What happens after four years?
After four years, you will be eligible to apply to live here permanently as long as you continue to meet the requirements of the Immigration Rules for United Kingdom ancestry and you have worked for four years continuously in the United Kingdom.
