An employer has to want to hire you for a job that qualifies for a visa. H1B visas for parttime jobs are possible but the processing, costs, and compliance obligations are the same as for fulltime jobs.As part of the interview I need to share a job offer letter. My employer wants to write it but needs to know what all should go inside the letter. You must fill out the Part Time Temporary Appointment Authorization for Payment (P-14A) as well as the offer letter to the candidate. Employment Offer Letter Instructions. Exceptions to Job Announcement. Requirements. Job announcements for all classified positions an agency intends to fill must be listed in the Recruitment. Following is the letter format I got from my attorney. Is this OK to carry.
