is series 7 licence helps to get a job in the financial industry?

Having held a Series 7 and 63 license, I can tell you that you MUST have one to buy and sell stocks, bonds, and other types of investments. If you're not interested in selling investments but still interested in the field of finance, a degree in Investment Banking can open many doors for you and be quite lucrative.

You normally need to get a series 6 and 63 first then you can go on to get the other license.

Many companies have their own in-house publishing departments. These could be involved in marketing, public relations, proposal development, or, most importantly (to me), in-house and customer-centric product use/maintenance/training materials. Have you considered technical writing or editing as an option? It helps if you have some exposure to the appropriate technology, but it's not always a requirement. The pay is usually not too bad.

Yes it will. Jobs I have looked at in Brokerage firms require Series 7. It will put you one step ahead to have your Series 7. Jobs to do with trading, such as with UVest, Brokerage firms and even within the baking community will require Series 7 . Get it and go knock them dead.

Good luck

yes ... it's law if you sell or trade ...there are other licenses you'll need as well,, like series 63 series 8 for management

It does. You grammar will hold you back though. Take some English classes first.
