Countries have visa restrictions in order to check and control the flow of visitors in and out of the country and to prevent illegal immigration and other criminal activities. Forcing travellers to apply for a visa allows the authorities to vet potential visitors. For example, individuals may attempt to travel to a country with better economic opportunities in order to work illegally there.
Important Notice on Missing Documents: If a required document is unavailable per the country-specific guidelines in the Document Finder tool, you do not need to submit them to NVC. However, if you cannot obtain a required document for another reason, you must submit a detailed written explanation to NVC when you submit your other documents. The consular officer will then determine at the time of the visa interview whether you must obtain the missing document before a visa can be issued. As a general rule, any document that is listed as “available” on the Document Finder tool must be reviewed by a consular officer. Failure to obtain all required documents will delay your case.

Some of the work visas, more specifically the H-1B, H-1B1, H-2A, and H-2B also require your employer to have a certification from DOL. Your employer should apply for the DOL on your behalf before even filing the petition with USCIS. The U.S government requires this certification as proof that U.S employers need foreign workers. They have to prove that they cannot fill those work positions with U.S employees. In addition, the certification is needed in order to ensure that temporary foreign workers are not having an impact on job opportunities for U.S citizens in a negative way.


Due to the high number of applications that U.S Embassies receive, you should make sure that you schedule your interview as soon as you meet all the requirements. If you are younger than 13 years old or older than 80 years old, a visa interview is generally not required. As for people between the ages of 14 and 79, interviews are required, but there can be exceptions if you are just renewing your visa.
The contents of the site are superb and thanks for your good advice! However, I would like you to put me thru in this area. I don’t have an invitation letter to support my documents for the tourist visa and secondly how much money should I have in my bank account? Since there is no sponsor, will I have more chances to get the visa approved for Europe and USA Visa, though my company promises to give me employment letter and payslip?
Traditional visas can either be stamped or glued into your passport. If your visa is glued into your passport, it is usually a small document that includes your name, passport number, place of birth, reason for travel and expiration date. Stamped visas typically have less information on them. They usually only have the destination and date from which the visa is valid and official instructions stating how many days the visa is valid for.
Certain conditions and activities may make an applicant ineligible for a visa. Examples of these ineligibilities include: drug trafficking; overstaying a previous visa; and submitting fraudulent documents. If you are ineligible for a visa, you will be informed by the consular officer and advised whether there is a waiver of the ineligibility available to you and what the waiver process is. Ineligibilities and Waivers: Laws contains the complete list of ineligibilities.

Any derivative applicant whose financial support is coming from a joint sponsor or household member who is not also sponsoring the principal applicant must also bring to the interview a signed Affidavit of Support from that joint sponsor or household member, along with the financial evidence necessary to show the sponsor’s income level and legal status in the United States. Applicants may bring photocopies and scanned versions of signed Forms I-864 and associated documents. (Please note that the form must still be signed; typed names and electronic signatures will not be accepted.)
If you are a digital nomad who is slow traveling through Europe and plans to spend more than 90 days in Spain, you need the "Residence Visa for Investors and Self-Employment." This visa allows you to reside in Spain and work, provided you have contracts that originate elsewhere. You cannot work for Spanish employers while you are in Spain on this visa.

Consequently, Australian citizens can visit the above Schengen member states visa-free for periods of up to three months in each country. If, however, an Australian citizen then visits another Schengen state not included in the list above, the restriction of no more than three months out of a six-month period in the Schengen area as a whole applies. Therefore, if an Australian citizen has already spent three months in one or more of the above Schengen countries, any visits to another Schengen country without a bilateral visa waiver agreement with Australia may lead to difficulties with local law enforcement agencies (e.g. being accused of having overstayed upon leaving a Schengen country which is not in the list above).
Tips for Schengen: Add buffer days to your itinerary for visa purposes. I had made flight booking just a day before the appointment and cancelled it a few hours after the appointment, cancelled hotel bookings only after getting the visa. All my real hotel bookings were done in anticipation of getting visa on exactly the dates I had mentioned on the application, so it is going to work out okay!! Europe here I come 🙂 GOOD LUCK to everyone! And THANKS AGAIN for your timely response and valuable advice!
Azerbaijan also strictly bans any visit by foreign citizens to the separatist region of Nagorno-Karabakh[633] (the de facto independent Republic of Artsakh), its surrounding territories, and the Azerbaijani exclaves of Karki, Yuxarı Əskipara, Barxudarlı, and Sofulu which are de jure part of Azerbaijan but under the control of Armenia, without the prior consent of the government of Azerbaijan. Foreign citizens who enter these territories will be permanently banned from entering the Republic of Azerbaijan[634] and will be included in their "list of personae non gratae".[635] As of 2 September 2019, the list mentioned 852 people.
