The most important thing when preparing for your move to another country is to secure the necessary documents. You should do this beforehand. Remember that documentation requirements and procedures are detailed, complicated, and often subject to change, thus, you have to apply to the embassy of the country you are going to move. Ask about all needed documentation, including passport, visa, permits, and registration requirements.
Furthermore, it is also important to determine from the consulate exactly what papers, documents, forms, and other information you will be expected to complete or provide. Check back with the consulate periodically to be sure that your information is up to date. This is because documentation regulations may change on short notice.
 A passport is essentially an identity document issued by governments to their citizens for travel outside their home country. This is an official verification of the nationality of the holder and, with a few exceptions, is required to enter another country. And very often it is impossible to issue a visa unless the applicant has a passport. Every passport should be valid for a period of time well into the intended stay in your destination country or longer. If your passport is due to expire during the period of your stay, then the entry to the country may be refused. Thus, before leaving, check with your destination country's nearest consulate for this information.
You must have a valid, unexpired passport. Keep it and other important documents in a safe place, such as a bank safe-deposit box. If your passport has been stolen or lost then report to the police. If you have a new passport and your valid visa is still in your old passport, you must use both passports. |
