I need some help in choosing the best University. I am currently done my Bachelors degree in Network Communications Mgmt at Devry in Canada.. I want to do Master in Information Security in the US.

Is it good program to do Master? How about employment rate. Can anyone recommend a good university.

Pls any suggestion.

I have a question regarding student visa.

I am a Canadian citizen and would like to study in USA for a shot time. If I study in US will they give me a green card so that I can search for a job while I am studying or will they give me student visa.

What way is better to get into the us to work.

You are head of the program committee for the local chapter of a professional society (DPMA, IEEE, APICS, or similar body). Your committee brings in guest speakers and creates other interesting and informative programs once a month for chapter members. Several months ago, the committee scheduled Leonard J. Bruce III, president of Medusa Computers, to make a two-part presentation on "Entrepreneurship in the Computer Industry."

Mr. Bruce's first speech last week was a disaster. He apparently had not prepared for the occasion and didn't seem to know exactly whom he was addressing. His topic had some potential, but the delivery was so disorganized that the audience became restless. Many of his comments were off-topic, touching on everything from his favorite Star Trek episode to his golf game. One of his jokes was flagrantly tasteless.

During the coffee hour following the presentation, you overheard a member say, "I'm not sure I want to attend next month's event." You also heard comments about the inappropriateness of the speaker's jokes. Although your first instinct is to cancel the second presentation, you realize that Mr. Bruce has already been paid a fee of $1,500 for two presentations and that his company is a major purchaser of products sold by the company for which you work. If your boss were to hear that you "fired" Mr. Bruce, things could get difficult for you at the office.

Directions

You discuss the problem with the chapter president, Allan Agrawal, who is sympathetic. He suggests three possible options for addressing the issue: you can fire Mr. Bruce, you can do nothing and let Mr. Bruce continue, or you can coach Mr. Bruce before the next speech. Decide on a course of action and write a memo in which you communicate your decision to Mr. Agrawal and the chapter’s Executive Committee. The secondary audience for your memo is your boss, Florence Milano, President of Data Solutions, Inc.

1. do you think that change allows you to learn new skills that will help move you forward?

2. what about the people that refuse to change? How can you handle them?

I need some help with this problem. About two weeks backs I gave someone a loan for $ 1500 + $ 300 ( interest ) they promised me that they will pay $ 225 weekly 8 payments but until now they have not yet paid me two weeks of payment. It was a wrritten agreement so I have their info such as personal like sin no, drivers no, home address, etc. Can the police help me out or please give me helpful info on how to get my money back.
