Very warm congrats to you and your family
What a fabulous thing to do, and something I've also recently undertaken.
It's a long and sometimes unnecessarily difficult process, though, given the Government says it's doing everything it can to encourage and expedite citizenship.
I began my process back in September/October, had my interview in November and won't have my ceremony until the end of April
I've lived here, paid taxes, done all the other things (except vote) that regular Aussies do for 23 years since my family migrated from the UK back in the early 80s. Yet, it wasn't as easy as I thought it would be to get through the citizenship process.
Anyway... come April 27th... it'll all be worth it
I'm not doing any of this for any other reason than I believe it is the right thing to do, and that Australia is... and will remain... my home.
