These are not visa categories. They sit beside the visa file: an appeal against undesirability, or a waiver that unlocks a later application.
Overstays & Undesirability
An overstay is remaining after a visa has expired, whether the overstay was intended or not. At a port of exit the immigration officer issues a declaration of undesirability. It records personal details, the number of days overstayed, the declaration, the period of the bar (ordinarily one or five years), and how to appeal.
From the date of the notice, the foreigner has ten working days to lodge an electronic appeal, with reasons (a pending application, medical cause, an airline change) and supporting papers: passport biodata page, the undesirability letter, and the documents that explain the overstay.
If the appeal succeeds, an electronic letter lifts the bar and the person may re-enter. The Act contemplates a decision within ten days; in practice the backlog is longer, and follow-up is required. We prepare the appeal or take over a file that has gone silent.
Waivers
A waiver is a formal request that the Director-General overlook a requirement the applicant cannot presently meet — for example, having to leave the Republic to lodge, or a SAQA evaluation required for a critical-skills visa. All other requirements of the visa must still be met.
For a business visa, a waiver of the R5 million capital requirement needs approval from both Home Affairs and the Department of Trade, Industry and Competition. Where several employees of one organisation need the same condition waived, a blanket waiver can be the economical route.
Waiver processing is commonly eight to twelve months. The applicant must hold a valid visa throughout if already in South Africa. We prepare waivers, including section 30(1)(h) good-cause matters, well ahead of the visa they are meant to unlock.
Appeals against refusals and High Court proceedings to compel a decision sit under Legal Services — Immigration Law Consultation, not on this page.
