I have my green card since June 30, 2001 and stayed in the US till December 2003 before leaving for India to attend to my father diagnosed with cancer. I have since been residing in India, visiting the US every 6 months or so to maintain GC. My wife got her citizenship in 2006 since she stayed back here in the US. I would now like to consider applying for citizenship - what is the minimum duration I need to be physically present in the US before applying?

My husband is on H4 with an I94 valid till June 17, 2011 and I am a H1B visa holder with a valid petition document. I am planning to go for a vacation. Will it be a problem if I leave my husband (dependent) in US and go for a vacation and come back in 3 to 4 weeks?

I got my H1B approval on 31 Dec 2010, thus my visa status changed from F1 to H1B (I am currently going to grad school and graduating in April 2011). My company wants me to get my visa stamped. I have heard various stories about problems faced in Canada for first time stamping. Is this really an issue? Is there any law which prevents us to get first time stamping done in stamping done in Canada?
