i am a flight attendant trying to apply for citizenship.. is there a minimum amount of time I was required to be in the country

 In order to apply for citizenship in the United States, the applicant must be a green card holder for a period of five years. if the applicant is married to a US citizen, they only need to be a green card holder for 3 years. Depending on the amount of time you have spent out of the country due to your job, you may be required to provide additional evidence with your application to prove that you have not abandoned your residency while away on work.
