N470 & Re-entry permit

[nandan123]

It would be extremely appreciated if some folks could help me out. This is my predicament for which I need your clarifications. I had my Green card approved on 06/01/06. I had been in US continously as a Permanent Resident since then till now with just a break of one week in from April-11, 2007 thru April-18, 2007 where I had to accompany my clients on their offshore trip. So calculating, my physical presence in the US till now would be around 15 months.
I am planning to work in India in 2008 for around 1 year due to personal reasons and then come back to USA. My firm is incorporated in the USA and I am being transferred to their offshore facility. I do not want to lose continuity of residence for naturalization purposes. So I am requesting my organization to file N-470. I am also planning to apply for re-entry permit before leaving in Jan 2008.

Please let me know if I am eligible for N-470, my only worry is the one week break in April. But my physical presence in US excluding the absence is around 15 months now and it will be around 19 months when I plan to leave USA.

Is there anyother special precautions that I need to take? I will be leaving in Jan-2008. When should I apply for N-470 and Renentry permit.

Please advice and help me out.
