So you have found a market that you want to write for.  The money seems good,  your idea is a perfect fit, and you are ready to pitch.  Hold on a second and take the time to check over some of these tips to make sure you have everything ready that you will need to succeed.

Part Two - Keys to Success
Before you pitch a foreign market, there are a few things that you will need to have prepared in order for any working arrangement to run smoothly. 

1. A good understanding of the local dialect.  Although the English language may be the common denominator for all of the countries you are targeting, spelling and word usage vary hugely from region to region.  Whenever I am on this topic I am always reminded of my poor friend who, while standing in line (queuing) outside a British cinema bemoaned loudly that she had chocolate melting in her pants.  While this was an innocent enough comment to any American about the candy bar wilting in her pocket,  the facial expressions on the British people around her changed visibly, with eyes widening and mouths tightening to suppress either giggles or distaste over this Yankee who not only had chocolate melting in her underwear (pants being knickers) but in that strange American fashion felt the need to share this publicly.

   While you can switch the language preferences in Word to check your spelling, other differences are more subtle:
   

   quite (British) really (US)

   It is common to use 'quite' in British English and 'really' in American English to mean 'very'.

   Example Sentences

   British: It's quite hot today. American: It's really hot today.
   American: That's really expensive! British: That's quite dear!

   Read a few articles from national newspapers and magazines to get a feel for the language usage.  Since reading back issues (or at least the online articles) for any publication you are writing for is a best practice anyway, then this shouldn't pose a problem. 

2. An understanding of the local culture can be beneficial too.  Again, knowing your market should be part of your pre-pitch routine, and you should always do some basic research to make sure your writing is appealing and appropriate for the people who will read it.  Are there any sensitive or taboo topics that you will have to break out your kid gloves for?  Your editor may be able to give you some guidance,  but don't expect them to spoon feed you information otherwise they will be better off working with a local writer.  Check for recent local news stories on your topic, or test the water in regional community message boards and forums.
3. A way to be paid is a must!  Have a Paypal account that can accept different currencies, and check with your bank for details on accepting international money transfers.  Can you deposit an international check in your account?  Knowing the exchange rate and banking fees will help you to decide which markets are financially viable to write for.
4. Good communication.  Email is the way to go here,  but having an internet phone such as Skype set up is a good idea too.  This will also allow you to make long distance phone calls affordably without using your regular land line.
