I am a US citizen married to a filipina citizen. She is working as a RN in Canada. She has lived and worked in Canada for 7 years. She is applying for her Canadian citizenship. She wants to be a dual citizen of Canada and the Philippines.
However, we want to live in the US. Can I sponsor her with a spouse visa IR-1/CR-1? Can she stay lawfully as a permanent resident? Will she have to give up one of her two citizenships?
What is the best course of action so we can both live and work in the USA?
