While you may have held a green card for over 5 years, frequent travel outside the U.S. can affect your eligibility for naturalization. USCIS requires continuous residence and physical presence in the U.S

You might still be eligible, but it depends on how much time you’ve spent outside the U.S. Being a green card holder for 7 years is great, but to apply for citizenship, you need to have actually been in the U.S. for at least 30 months in the last 5 years

Maybe, but it depends on your travel. To qualify for naturalization, you need to have spent at least half of the last 5 years physically in the U.S.
