Canada has closed it 边境 to Foreign nationals who have been traveling from the Schengen space prior to their arrival in Canada so this is no longer an option.

除了, 截至3月21日, 2020, there is a 30-day restriction on all non-essential travel at the Canada-U.S. 边境

这是州法与百老汇4001最新网站法的问题. Many states (like New York or California) allow unemployment benefits even to foreign nationals, 只要他们被授权在美国工作.S.  

这似乎与美国百老汇4001最新网站局的规定直接冲突, 这使得在美国工作是一种有效的状态.S. 
‍
尽管这很矛盾， if it became necessary for someone in a temporary visa status (E, TN, L-1A or O1) to apply for unemployment benefits then he can do so [see more details below). 
‍
值得注意的是，对于那些 H-1B, the employer is in theory always subject to paying the prevailing wage (DOL's rule) and going on unemployment would be in contradiction of that so in case of change of salary, it would be recommended to amend the existing petition to reduce the number of hours and thus salary. 

Grace period: As an employee under a non-immigrant visa status, 如果你被解雇了, you are allowed to stay a 60 day grace period in the United States, period during which you may seek sponsorship for an employment-based visa status with a different employer.
‍
根据免签证计划在美国的人 who are nearing the end of their 90-day stay may apply for a special extension of their stay called “satisfactory departure”. 这种令人满意的离境可以延长30天. The main reason to be considered must be related to health issue due the COVID.

失业 is NOT considered to be a public benefit under the new public charge rule.

The rule explicitly lists benefits that can be considered in the public charge analysis, which are (Supplemental Nutrition Assistance Program (SNAP), 补充保障收入(SSI), 援助有需要家庭临时助理人员, 大多数形式的医疗补助, 以及一些住房援助项目. Notably absent from this list are state-funded programs and unemployment insurance.
‍
Note also the USCIS's own website which states that services received by noncitizens related to COVID-19 should not negatively affect the public charge analysis:

• 美国百老汇4001最新网站局鼓励所有这些, 包括外星人, with symptoms that resemble Coronavirus 2019 (COVID-19) (fever, 咳嗽, shortness of breath) to seek necessary medical 治疗 or preventive services.  Such 治疗 or preventive services will not negatively affect any alien as part of a future Public Charge analysis.  
  
• USCIS也不会考虑检测, 治疗, 也没有预防保健(包括疫苗), if a vaccine becomes available) related to COVID-19 as part of a public charge inadmissibility determination, nor as related to the public benefit condition applicable to certain nonimmigrants seeking an extension of stay or change of status, even if such 治疗 is provided or paid for by one or more public benefits, 如规则(e.g. 联邦政府资助的医疗补助).
  
• USCIS considers the receipt of public benefits as only one consideration among a number of factors and considerations in the totality of the alien’s circumstances over a period of time with no single factor being outcome determinative.
