Need info on Limitation on business of Proprietorship firms

Hello,

I am running a company/firm under sole proprietorship. My business verticle is in Aviation & Hospitality Traning and consulting.

Now, as per my interest, I am willing to establish my company operations in Gulf countires. By launching Aviation Training academy with support of local partners. My first venture will be in Saudi Arabia, for which I have found a parnter company there, who will make 100% investment in setting up training academy.

However as per my condition, the entire operations and major controll of the company will be with the indian company, thats my firm. In return we offer them maximum profit share of that business and some percentage we will be taking.They will be even using our company name for business in Saudi with our permission. Our new venture will duely beregistered in Saudi as per their law.

What I need to know is:

Can a sole proprietorship company may engage in a business estabslihed outside India under the same firm name ? This is without making any investment outside. Is there any formalities for this ??

What kind of taxes will be applicable if I bring my profit percentage from saudi business ? Is there any easy way to save on taxes ?

To be on a safer side, should I make that project registered in Saudi as a Joint Venture, or make them our Franshisee, LLC or ......?? Please advice

Also, dealing with clients in India & abroad, lot of time wea re asked to proove our company registration, which is hard to furnish being a proprietorship firm. Apart from sales tax registration, is there anyw ay we could register some where in govt bodies to get a certificate ?? Or can we make a affidivit of being proprietor or for company ?

I will highly appreciate if the experts and give a detail comment on this.
