BREAKING: ACS "expresses concern" on President Trump's immigration executive order

It's politics time, folks. Don't want to read it? I won't be offended.

Ask CJ: Blighty to Canada

From the inbox, a Ph.D. organic chemist working in industry in the UK (let's call them "WHK") asks some immigration questions about Canada:

• How easy is it to find a job in Canada (senior chemist / group leader / lab manager or similar)?
• How can I compare my current salary in the UK with wages in Canada?  What about house prices?  
• In the UK, we have the NHS; how does the system work in Canada?  
• Who sorts out visas, me or my prosepective employer? Are visas easy to get?  
• What about citizenship, should I bother?  
• Where would I most likely get a job in Canada (BC, Toronto, Quebec)?  

I still don't know enough about the Canadian pharmaceutical/chemical industry to answer this question competently. Readers, any thoughts? 

(For the Americans in the crowd, "Blighty.") 

Ask CJ: an immigration question

I recently received an e-mail from AS, who got a Ph.D. in chemistry in the US* and did a postdoc here as well, but through happenstance, is back in their home country in Eastern Europe. They're looking for ways to find industry jobs in the US or other countries. They have the following questions:

• Is there and difference in the difficulty level of finding employment for foreigners between US and Canada? 
• Alternatively, I can try to find another postdoc (which is something I am also working on). However, due to certain visa policies I can not return on the same academic visa I had previously. Do you happen to know if new or returning postdocs are admitted back in US on a temporary work visa? 

I confess to not being an science immigration expert, but I am sure there are some amongst my readers. It is my broad understanding that Canadian immigration is more biased towards skills-based (or $$-based) policies than those of the US, but I confess I don't really understand the issues.

Please comment, if you have expertise.

*At a very good department, not that it matters.
