Why do Migrants face Challenges?

Today in class we got a packet "Why Do Migrants Face Challenges?" and some of the notes that I took were....

• A migrant needs a passport to legally emigrate from a country and a visa to legally immigrate to a new country 
• Most countries have adopted selective immigration policies that admit some types of immigrants but not others 
• Two reasons that visas aren't granted is for specific employment placement and family reunification 
• The U.N. classifies four types of immigration policies:
1. maintain the current level of immigration
2. increase the level
3. reduce the level
4. no policy, Similarity, emigration policies are identified by the same four classes
• Unauthorized immigrants- Immigrate illegally
• Undocumented immigrant- some of the groups that advocate for more right s for these individuals 
• Illegal alien- some of the groups that favor tougher restrictions and enforcement of immigration laws
