apply for 470 form

[GAMA2003]

we are going to move out of US due to a oversea employment assign by our company.

Could we file 470 for keep the eligibility of applying for citizenship.

After we get GC for 1.5 year, I travel 3 short trip for 2-3 week period outside of USA. does that disqualify my eligibilty for 470?

What should I do?

thanks
