If you are planning to emigrate then you have lots of things to prepare and decisions to make. Your current situation will go a long way to deciding lots of things for you. Choosing where you would like to move to is, of course, a huge part of the decision making progress. You may have lots of reasons for wanting to move. Maybe you feel you have put it off for long enough or maybe an opportunity has presented itself that is simply too good to resist. Whatever your reason, there is still a lot to consider.
Your family and friends will probably be in the front of your mind, especially if you are leaving them behind. Choosing somewhere to live that will offer them a place to stay when they visit you is a good idea. If you cannot afford a large enough house to offer them accommodation when they visit, you could choose somewhere with local amenities to suit their needs too.
If you are planning to buy abroad then selling your own property is probably the best way to fund the move. Do a little research to figure out what you can expect to buy abroad from the proceeds of your house sale. Depending on where you are planning to move to, you may be pleasantly surprised by what is on offer in your price range. You will certainly have fun spending the money in your head on lots of different houses before you find the right property for you.
If you are giving up your job to move abroad then you need to think about how you will support yourself once you move. If you are planning to emigrate to Australia then you need to have a skill that is useful to them and enough money to support yourself. Many countries will insist you have a visa before you can even visit them. Do your research and seek professional advice before you take the plunge.
Whatever your plans, this is probably going to be the biggest and most exciting move you will ever make. Think carefully about your decision and try to visit your chosen country at several different times of the year before you commit yourself to anything. If necessary, learn the language or at the very least learn the basics you will need to get by. Make an effort to meet some local people and understand the way of life there. If you are a person who likes everything done yesterday then some cultures may be too laid back for you.
