Joining us in The Deep End today is Sophie Alcorn. Sophie is the founder of Alcorn, a Silicon Valley immigration law firm that helps tech talent immigrate to the US. She is also the host of the podcast Immigration Law for Tech Startups and author the TechCrunch weekly immigration advice column “Dear Sophie.” Continuing with our series on the meta-problem of helping people start more companies, we talk to Sophie to understand why immigration is a bottleneck to company creation, and what founders, investors, and policy-makers can do about it.
