Staying out of the US for 1 year - returning every 6 months for how much?

[touyats]

Hi,

I left the USA on Sept 1 to go back to my country helping friends who are starting a business (for free, so I don't have any paperwork that can show the reason why I'm out).
I was planning to return to the USA in January, so it would be less than 6 months out, however, they asked me to help till summer, so I'm considering coming back for some weeks to break the 6-months-at-most out of country limit for naturalization.

I think immigration officers have the right to deny naturalization for any reason, but is there a "safe" period of stay in the USA to make it less likely the two 6-months period not to be considered one?

You can stat outside USA less than 6 months safely. So if you stay outside 6m then come to USA for few weeks and going back is not safe.

Is there a recommended period of stay in the USA between the less-than-6 months absences?

It may not be so strightforward. See here:

Recently this text has been added:

An officer may also review whether an applicant with multiple absences of less than 6 months will be able to satisfy the continuous residence and physical presence requirements. In some cases, an applicant may not be able to establish that his or her principal actual dwelling place is in the United States or establish residence within the United States for the statutorily required period of time.
