Immigration and Problems
Hundreds of thousands of people supporting immigration rights in the US filled the streets all over America
in early 2006.Many held signs and American flags and asked to be treated as citizens一not criminals.Many
of these people supported legislation from Senator John McCain that would open a path to citizenship to immi-
grants who were already in the country illegally.Proposed legislation from other politicians called for stricter
measures一including rounding up undocumented immigrants and sending them back to their home
countries.
Canadian officials say that immigration applications continue to rise.Some want to keep the doors open.
They need the labor. About 400,000 immigrants were allowed into the country in 2005,according to the
Canadian Government statistics.However,all this growth means that cities need to adapt.New-corners don't
always make a smooth transition into jobs at which they are skilled. So industries are using mentoring(辅导)
programs to help new immigrants find proper jobs.
With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing
no sign of abating(减少), the Spanish Government has decided to get tough. There will be no more mass
amnesties(特赦)for illegals,and anyone coming to Spain without permission will be sent back,the govern-
ment has announced. About 23 ,000 migrants(移民)landed on the islands in 2006 , and riots have enipted ir
some crowded reception centers.This has promoted local authorities to appeal to the United Nations for help.
France's new immigration and integration law gives the government new powers to encourage high-skillec
migration.It took effect in 2007.The new law authorizes the government to identify particular profession,
where France has a talent shortage.Then the government will help these identified employers find immigran
workers with needed skills or qualifications.The selected foreign employees will be granted"skills and talents'
visas,valid for three years.But some people show the concern that. it'll cause brain drain in developing countries.
Many immigrants in the US took to the streets in early 2006,demanding that_______.
A.John McCain be removed
B.they be sent back home
C.they be treated as citizens
D.their culture he protected
