My mother has valid 10 year tourist visa. However, on tourist visa, she can stay upto 6 months in US. I wanted to know that after 6 months, can she fly to Canada for a month to stay with her sister and then return to US after a month. What's the min time limit she has to be out of US in order to re-enter US?
I'm having a small child and would like her to stay with me as much as possible.

I-485 pending and after 6 months (so AC21 portable). Laid off. H1-B revoked but I-140 not revoked. Since it was very hard to find a job in US, I found a job outside the US temporarily in Sept 2009 and stayed there till now. Can I still enter US on AP?

I had my interview today.The officer asked me simple direct questions like my DOB,when I came to USA ,when I moved to this state..then on the trips section he said "what was your purpose of your visits, becuase I see trips for like 3 months "i said " i visited my husband and relatives"and thats it on this section,given that i made 6 trips out,the longest is for 5.5months after civics,he said I passed,but no decision was made because they need to review my physical residency. Is my case very bad? I am worried!total days spent out were 554(1.5yr)in my 5yr residency!how bad is that? do they take long time to respond?

I am supposed to apply for my business visa today for USA. I am traveling for pure business, meeting my existing suppliers and doing further business development and also inspect a loading on existing contract. I will be providing relevant business details on my visa form. The small query that i have is, that my real sister is based in usa, and her husband holds a green card.the visa form asks for mentioning of any blood relation/relative settled in usa, so would mentioning their details on my visa form create some kind of hindrance in my getting the business visa?

My wife and I have decided that marriage does not fit into each others dreams anymore. We have been married for almost 3 years and Just got a notice that after filing I-751, the evidence submitted with the form was "insufficient". Our marriage and relationship started and continued in the utmost manner of good faith. Our decision for divorce was a mutual one. We plan on continuing friendship in good faith and she will always be part of our family. She has a life here, she works hard, pays taxes and wants to continue her life here. We both don't want her residency here, her life, stripped away.

I am a Filipina and I have my fiance in the US but he is still waiting for his greencard. We are really looking forward to be together soon. Which is more easier to get a visitor's visa or a fiance visa? But he is not a US citizen yet, he is still waiting for his greencard. Please tell us what would be the best for us to do in order for us to be together soon?
