If you have a condition or characteristic that the U.S. government has decided undesirable or would threaten the health and safety of people living in the United States, you are inadmissible. The U.S. government keeps a list of the conditions and characteristics that make a person inadmissible. (See I.N.A §212, 8 U.S. Code § 1182.) In obtaining a waiver, you don’t try to get rid of or disprove the ground of inadmissibility. Instead you ask the immigration authorities to overlook the problem and give you a green card or visa anyway.

如果您的个人情况是美国政府认定不受欢迎或威胁到美国居民的健康和安全的，则对您的案件不予受理。 美国政府列出了使某人案件成为不予受理的条件和特征。（参见移民和国籍法案§212,美国法典第八章§1182。）这种情况下您需要申请豁免。在申请豁免时，您不是试图摆脱或反驳不予受理的理由。 相反，你要求移民局忽视这个问题并同意受理您的绿卡申请。

Different terms may confuse some people with advance parole and reentry permit. Ask yourself whether you are waiting for the approval of the I-485 Adjustment of Status, or you are already a permanent resident.

Before starting the whole EB-2 or EB-3 green card application, your employer needs to go through a process called PERM. Your employer needs to request Prevailing Wage Determination (PWD) for a position within a specific area at that time from the U.S. Department of Labor, using the Internet-based iCert system. The PWD will typically expire within a year or less, so It will be important to recruit for and file the PERM labor certification soon after the PWD is issued.

在开始整个EB-2或EB-3绿卡申请之前，您的雇主需要经历一个称为PERM的过程。 您的雇主需要使用iCert系统，向美国劳工部申请某一时间、某个区域对于某个特定职位的现行工资标准（PWD）。 现行工资标准通常会在一年或更短的时间内失效，因此，在现行工资标准确定后就应该开始打广告和提交PERM劳工证申请，这一点很重要。
