Employment and travel on GC

[pretty_diya]

I got my GC in September 2008.

Traveled to India for --

2 months March to May 2009.

2months January to March 2010

5months, 15days June to December 2011

Currently in India April to September 2012 (5.5months)

In the above 4years since I got my GC, I was employed only for 1year. I received the GC as dependent spouse.

I paid taxes for all years and had residence and bills etc.

Next year in September 2012(5years completing on GC status), will I be eligible for citizenship?

Also, can I apply for re-entry permit without affecting my citizenship application?

I have been divorced with my husband and had medical problems due to which I could not maintain continuos employment.

I want to come back to India and take rest. Maybe even take up a job.

Please advice. JoeF, kindly advice.
