So my sister has lived in USA for 3 years out of the last 3.5 years in USA since receiving Green Card. As far I am concerned she has already completed the 30 months requirements.
She recently got married and hence planning to stay abroad with her husband in Canada for the next 1 year - 11 months out of 12 months with 15-20 days of returning to USA before every 6 months to not stay abroad for more than 180 days.
She is planning to return to USA on her 4.5 years and stay continuously 6 months so she can apply for naturalization.
1. Is it mandatory to stay 180 days out of 365 to be eligible for naturalization? Someone advised her that's the case. The lawyer in question saying if she doesn't stay for 6 months in USA in a year, she won't get US passport. Is this correct?
2. Her husband is planning to apply for her Canadian PR. She is expected to become Canadian PR before she reaches 4.5 years. Will that have any adverse effect on her naturalization process? Does getting a PR of another country makes it harder during USCIS interview or her intent to become US citizen?
3. On her last year, she will be away for the first 6 months. Then 6-9, the 3 months she is planning to stay in USA to be eligible for naturalization. Is this fine and can she apply for naturalization after her 9th month and obviously she will stay the rest of the 3 months on the same state?
Thanks!
