B-1 Visa

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?

I have already applied for the draw for the Diversity Lottery Visa for which I am eligible.If at all I dont get selected and want to make a B1/B2 application thereafter will I have to mention in the application form that I have been denied such a chance for lottery before and if I choose not to do so can the consulate people find out that this person has made such an application before.Please advise for the correct approach.

I am a U.S citizen but my husband is not yet. My mother in law has been battling cancer for a while and I would love for her to come here and get medical treatment and to just see her grandson. She is from El Salvador, is there any way for us to do that?

Last november 11, 2009 I went to seattle for vaccation. I detained: 1-one returned ticket for may 3, 2010; 2-one electronic ticket for one mission on geneva from december 1st to 7, 2009; 3- 3books for my online MBA courses; 4- one visa B1 & B2 for 10 years issue on july 2007, 5- a letter for my employer. But when I arrive to airport the immagration office say that I came to work or study, but not for vaccation. They put me in Jail ARROUND 1 MONTH and they revoked me.
I want to know the way to make my complaint and ask to review my case. I am an international worker since 1999.

Have a pending I-130 with priority date of 26 OCt 2002 In the F2B category, now my cousin wish for me to visit her in MARYLAND, My parents and siblings live in the states and I have been denied B2 Visa befor in 2002 , but I have also travelled to the US before as a child first in 1987 and 1992 with my father. QUESTION is I have 5 Years working experience in a bank, I have travelled to the UK,FRANCE,ITALY AND SPAIN regularly on holidays in the last 3 years. What are my chances of getting a visitors visa? If my chances are not bright, I might as well forget about applying for a visitors visa.

I came back from states in 2003. I had mulitiple b1/b2 visa that was expired in 2006. Now, if I apply again so what are the chances? Can i get multiple visa again?

I am an amateur singer who has had an american label interested in carrying my CD's (this is my first CD, and I have never been paid for my music before). They intend on having me appear on shows on radio and tv nationally, and to do press, both by doing interviews and performing. Would I qualify to do interviews and perform for national tv shows under a B1 visa, since I am still an "amateur" singer? Or am I NOT an amateur just because a major label is carrying my CD?
