B Visa

I am a UK resident and currently have a B1 visa with 7 years to run. When I enter the US via LAX they always stamp my passport and issue the I-94 card for 12 months. We always leave before the date given. Question - do we have to go back to the UK (our country of origin) or could we go to Canada for a week and then re-enter the US?

I am working in a Federal Gov't Agency, and in the near future leaving for Frankfurt, Germany, for a conference, and with a plan in mind to fly to USA via Germany after my conference is completed. My question, here, is that whether I can use my US visa, which is valid up to Apr 06/2012, whereas the passport has already expired by last May 23/2011, and due to be replaced by a new one.

I have a brother here in US who is diagnosed with cancer. I would like my mom and brother who live in India to come and visit him. What type of visa should they apply for in India and how long will it take? On which visa can they come as soon as possible.

My mother wants to travel to US on her existing visit visa. We recently filed for her GC petition as well. We are wondering if she is allowed to travel on that same visit visa. Her visit visa is also expiring soon, would that be a problem coming into USA?

I am US citizen and my wife is here on B-2 visa, her I-94 just expired, applied for extension, denied. Can I file I-130 and 485 for her now and can she wait here for her GC legally without leaving the country?

I have plans of taking the FOREIGN PHARMACY EQUIVALENCY EXAM (FPGEE), I am from the Philippines what kind of visa should I apply for?

Can I invite my parents while I am on a business visit. I have I-94 valid till June 2011. My dad is a defence employee.

I'm a non-married Iranian citizen who’s my first-degree family members are US citizens, currently residing in USA. During last several years I've been rejected every time I requested for a US visa (both F and J).
Now, I am qualified to become a Canadian PR through the skilled-worker program. The visa is issued and I will be soon landing in Canada. I was wondering if my chances for getting a B-2 visa to visit my family will be any better once I'm a registered Canadian resident. Is it wise to ask for a visa once I get my PR card?
