What are the 20 13 investment migration trend forecasts?

In 20 13 years, although the mainstream status of Canada and the United States will not change, countries such as Europe will gradually seize some market share, and the choice of immigrant applicants will be more diversified. The high-profile involvement of European countries will further change the pattern of investment immigration market. Although most of the immigrant visas granted to applicants by European countries have certain conditions, the advantages of the European Union make applicants free to travel to all EU countries as long as they get the green card from Schengen countries, and the added value of the green card will attract many people's attention.

General situation of American geography

Geography:

The United States is located in the south of North America, bordering the Atlantic Ocean in the east, the Pacific Ocean in the west, Canada in the north, Mexico and the Gulf of Mexico in the south, and its territory also includes Alaska in the northwest of North America and the Hawaiian Islands in the middle of the Pacific Ocean.

It covers an area of 93726 1.5 million square kilometers, 4,500 kilometers from east to west, 2,700 kilometers from north to south and 22,680 kilometers from coastline. The whole territory can be divided into five geographical regions from east to west: the southeast coastal plain is divided into two parts: the Atlantic coastal plain and the Mexican coastal plain. This area is below 200 meters above sea level, and most of it is formed by alluvial rivers, especially the Mississippi River Delta, which is the largest delta in the world with fertile black soil. There are some swamps near the estuary. Located in this geographical area, Florida Peninsula is the largest peninsula in the United States.

The Appalachian Mountains are located on the west side of the Atlantic coastal plain, basically parallel to the coast, with a total length of more than 2,300 kilometers and an altitude of 1 1,000 ~11,500 meters. They consist of several parallel mountains. The inland plain is an inverted triangle, starting from the long border between the United States and Canada in the north and reaching the Rio Grande in the Atlantic coastal plain in the south. The western mountains include two mountains in the west, the Rocky Mountains in the east, the Sierra Nevada and the Cascade Mountains in the west. The product of the old folding movement. Mount Whitney in the Sierra Nevada is 44 18 meters above sea level, which is the highest point in the continental United States. Mount Rainier in the Cascade Mountains is 4392 meters above sea level, second only to Mount Whitney.

The western mountain plateau is composed of Colorado Plateau, Wyoming Plateau, Columbia Plateau and Grand Canyon, and it is the most complicated area in the western United States. Located in the northwest of Arizona, the Grand Canyon consists of a series of winding canyons and deep valleys. Magnificent momentum and steep rock walls are rare natural landscapes in the world. There are many rivers and lakes in the United States, and the water system is complex. Generally speaking, it can be divided into three major river systems: all the rivers flowing into the Atlantic Ocean east of the Rocky Mountains are called the Atlantic River System, mainly the Mississippi River, the Connecticut River and the Hudson River. Among them, the Mississippi River is 6020 kilometers long, ranking third in the world. Every river that flows into the Pacific Ocean is called the Pacific water system. Mainly the Colorado River, Columbia River, yukon river and so on. The Great Lakes of Central and Eastern North America. Including Lake Superior, Lake Michigan, Lake Huron, Lake Erie and Lake Ontario, with a total area of 245,000 square kilometers, it is the largest fresh water body in the world and is known as? North America Mediterranean? Among them, Lake Michigan belongs to the United States, and the other four lakes belong to the United States and Canada. Lake Superior is the largest freshwater lake in the world, ranking second in the world after the Caspian Sea.

Climate:

Most of the United States has a temperate and subtropical climate, and only the southern tip of Florida Peninsula has a tropical climate. Alaska is located between 60 and 70 degrees north latitude and belongs to the cold climate zone in the Arctic Circle. Hawaii is located in the south of the Tropic of Cancer and belongs to a tropical climate zone.

However, due to the vast territory and complex terrain of the United States, the climate varies greatly from place to place. It can be roughly divided into five climate zones: the temperate climate zone along the northeast coast. Affected by the Labrador cold current and the cold air in the north, this area is cold in winter, with an average temperature of -6℃ in June of 5438+ 10, and mild and rainy in summer, with an average temperature of 16℃ in July. The average annual precipitation is about 1000 mm. Tropical climate zone of Southeast Asia. Affected by the Gulf Stream, the climate is warm and humid, with1October average temperature1℃, July 24-27℃ and annual average precipitation 1500mm. The continental climate zone in the central plain. The region has a continental climate, with cold winters, average temperature of-14℃ in June and hot summers, and average temperature of 27 ~ 32℃ in July. The annual average precipitation is1000 ~1500mm. The arid climate area of western plateau. Last year, the inland climate in this area had a large temperature difference between the plateaus, and the annual temperature difference in the Colorado Plateau was as high as 25℃. The average annual precipitation is below 500 mm, the precipitation in plateau desert area is less than 250 mm, and it is a maritime climate area along the Pacific Ocean. This area is warm in winter and cool in summer, with abundant rainfall. 5438+ 10, the average temperature in June is above 4℃, and the average temperature in July is around 20 ~ 22℃. The annual average precipitation is about1500mm.
