The email from the atorney said "I am pleased to inform you that your ... application was approved. Congratulations on becoming a Lawful Permanent Resident (LPR).". It's been a very long wait, almost 10 years since we came to the USA, but worth it. No more worrying every time we want to go away on holiday whether we will be able to get back in to the country. Freedom to work wherever I want (not that I have any plans to move!). And the security of knowing that if anything happens to me, Donna won't be kicked out of our new home.
Now, five more years and we can apply for citizenship :-)
