B Visa

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?

I am an IT professional who has come to the US for medical treatment on a B2. I am getting better. Since I like to constantly upgrade my skills, I found some training programs that I could attend as they are more frequent in the US than in Canada. Can I attend them on a B2? I mean I have a B1/B2 visa, but the officer marked it as B2 on the stamp on my passport at the POE. Second - I also have got an offer for a one day lecture to some technology professionals for which I might get paid. How would the folks know I worked for a day if while exiting the country there is no checking?

My company has agreed to bring me and my wife to USA on L2 visa and then later get a H1 B visa. I want to make sure my parents have a B2 visa before I leave India. I have thought of two possible approaches:
a) Get a B2 visa for my parents but telling US consulate that I am traveling on business to USA and want my parent to visit the country. I used the same method for my wife 2 years back with no problems.
b) Get a L2/H1B visa for my self and then submit a request saying my parents want to visit the country for some time.
